In May 1861, three enslaved men who were determined not to be separated from their families ran to Fort Monroe, Virginia. Their flight led to the phenomenon of Civil War contraband camps. Contraband camps were refugee camps to which between four hundred thousand and five hundred thousand enslaved men, women, and children in the Union-occupied portions of the Confederacy fled to escape their owners by getting themselves to the Union Army. Army personnel had not envisioned overseeing a massive network of refugee camps. Responding to the interplay between the actions of the former slaves who fled to the camps, Republican legislation and policy, military orders, and real conditions on the ground, the army improvised. In the contraband camps, former slaves endured overcrowding, food and clothing shortages, poor sanitary conditions, and constant danger. They also gained the protection of the Union Army and access to the power of the US government as new, though unsteady, allies in the pursuit of their key interests, including education, employment, and the reconstitution of family, kin, and social life. The camps brought together actors who had previously had little to no contact with each other, exposed everyone involved to massive structural forces that were much larger than the human ability to control them, and led to unexpected outcomes. They produced a refugee crisis on US soil, affected the course and outcome of the Civil War, influenced the progress of wartime emancipation, and altered the relationship between the individual and the national government. Contraband camps were simultaneously humanitarian crises and incubators for a new relationship between African Americans and the US government.

Counterinsurgency (known as COIN) is a theory of war that seeks to describe a proven set of techniques that a government may use to defeat a violent, internal, organized challenge to its authority and legitimacy. The term is sometimes also used to describe the set of activities itself (e.g., “conducting counterinsurgency”). The term originates from the middle of the 20th century, when it emerged from officials in U.S. President John F. Kennedy’s administration, as well as from British and French thinkers and practitioners with whom these officials were consulting. The Kennedy Administration and its allies were grappling with how to deal with what they viewed as Soviet attempts to destabilize post-colonial governments in the Third World and bring those nascent countries into the Soviet orbit. Encouraged by British and French experience in post-colonial rebellions and prior experience of imperial policing, the Kennedy administration hoped to apply their lessons learned to Cold War problems, most notably the growing challenges in Vietnam.
Rebellions, “irregular warfare,” “guerrilla warfare,” or “small wars,” or for that matter, thinking about means to put them down, go back to the beginnings of organized conflict itself. But 20th-century thinkers were informed most especially by British and French theorists of the 19th and early 20th centuries, such as British Colonel Charles E. Calwell and future Marshal of France, Hubert Lyautey. The most significant influence came from veterans, such as Sir Robert Thompson, of Britain’s “Emergency” in Malaya, from 1948–1960, and from David Galula, veteran of France’s conflict in Algeria from 1954–1960. Though these theorists differ on a number of points and on emphasis, the intellectual paternity is clear.
At its heart, the premise of counterinsurgency theory is that rebellions can only be eliminated by gaining the support of the population. Because rebels can hide amongst the people, influence them, and convince “fence sitters” to join in an insurgency, the government can only succeed when the majority of the population rejects the rebels and their message, refuses to offer them assistance, and ultimately turns them over to the authorities. Counterinsurgency theorists often invoke an image from a work by Chinese leader Mao Zedong, On Guerrilla Warfare, in which he described the people as water and guerrilla fighters as fish swimming in it.
Theorists argued for decades (indeed, the argument goes on) about whether America’s war in Vietnam failed because the nation was unable or unwilling to fully implement proper counterinsurgency practices. When the U.S.-led wars in Iraq and Afghanistan in the 21st century began to falter, counterinsurgency and its proponents were once again center stage. Indeed, many maintain that, in 2007, the United States began to implement COIN, and that this turned the tide. But this argument remains in dispute, as do the theoretical and historical foundations of COIN more broadly.
The Creek Confederacy was a loose coalition of ethnically and linguistically diverse Native American towns that slowly coalesced as a political entity in the 18th and early 19th centuries. Its towns existed in Georgia, Alabama, and northern Florida, and for most of its preremoval history, these towns operated as autonomous entities. Several Creek leaders tried to consolidate power and create a more centralized polity, but these attempts at nation building largely failed. Instead, a fragile and informal confederacy connected the towns together for various cultural rituals as well as for purposes of diplomacy and trade. Disputes over centralization, as well as a host of other connected issues, ultimately led to the Creek War of 1813–1814. In the 1830s, the United States forced most members of the Creek Confederacy to vacate their eastern lands and relocate their nation to Indian Territory. Today, their western descendants are known as the Muskogee (Creek) Nation. Those who remained in the east include members of the federally recognized Seminole Tribe of Florida and the Poarch Band of Creek Indians who live in Alabama.
Distinctive patterns of daily life defined the Jim Crow South. Contrary to many observers’ emphasis on de jure segregation—meaning racial separation demanded by law—neither law nor the physical separation of blacks and whites was at the center of the early 20th-century South’s social system. Instead, separation, whether by law or custom, was one of multiple tools whites used to subordinate and exclude blacks and to maintain notions of white racial purity. In turn, these notions themselves varied over time and across jurisdictions, at least in their details, as elites tried repeatedly to establish who was “white,” who was “black,” and how the legal fictions they created would apply to Native Americans and others who fit neither category.
Within this complex multiracial world of the South, whites’ fundamental commitment to keeping blacks “in their place” manifested most routinely in day-to-day social dramas, often described in terms of racial “etiquette.” The black “place” in question was socially but not always physically distant from whites, and the increasing number of separate, racially marked spaces and actual Jim Crow laws was a development over time that became most pronounced in urban areas. It was a development that reveals blacks’ determination to resist racial oppression and whites’ perceived need to shore up a supposedly natural order that had, in fact, always been enforced by violence as well as political and economic power. Black resistance took many forms, from individual, covert acts of defiance to organized political movements. Whether in response to African Americans’ continued efforts to vote or their early 20th-century boycotts of segregated streetcars or World War I-era patterns of migration that threatened to deplete the agricultural labor force, whites found ways to counter blacks’ demands for equal citizenship and economic opportunity whenever and wherever they appeared.
In the rural South, where the majority of black Southerners remained economically dependent on white landowners, a “culture of personalism” characterized daily life within a paternalistic model of white supremacy that was markedly different from urban—and largely national, not merely southern—racial patterns. Thus, distinctions between rural and urban areas and issues of age and gender are critical to understanding the Jim Crow South. Although schools were rigorously segregated, preadolescent children could be allowed greater interracial intimacy in less official settings. Puberty became a break point after which close contact, especially between black males and white females, was prohibited. All told, Jim Crow was an inconsistent and uneven system of racial distinction and separation whose great reach shaped the South’s landscape and the lives of all Southerners, including those who were neither black nor white.

The history of DDT and pesticides in America is overshadowed by four broad myths. The first myth suggests that DDT was the first insecticide deployed widely by American farmers. The second indicates that DDT was the most toxic pesticide to wildlife and humans alike. The third myth assumes that Rachel Carson’s Silent Spring (1962) was an exposé of the problems of DDT rather than a broad indictment of American dependency on chemical insecticides. The fourth and final myth reassures Americans that the ban on DDT late in 1972 resolved the pesticide paradox in America. Over the course of the 20th century, agricultural chemists have developed insecticides from plants with phytotoxic properties (“botanical” insecticides) and a range of chemicals including heavy metals such as lead and arsenic, chlorinated hydrocarbons like DDT, and organophosphates like parathion. All of the synthetic insecticides carried profound unintended consequences for landscapes and wildlife alike. More recently, chemists have returned to nature and developed chemical analogs of the botanical insecticides, first with the synthetic pyrethroids and now with the neonicotinoids. Despite recent introduction, neonics have become widely used in agriculture and there are suspicions that these chemicals contribute to declines in bees and grassland birds.

Death is universal yet is experienced in culturally specific ways. Because of this, when individuals in colonial North America encountered others from different cultural backgrounds, they were curious about how unfamiliar mortuary practices resembled and differed from their own. This curiosity spawned communication across cultural boundaries. The resulting knowledge sometimes facilitated peaceful relations between groups, while at other times it helped one group dominate another.
Colonial North Americans endured disastrously high mortality rates caused by disease, warfare, and labor exploitation. At the same time, death was central to the religions of all residents: Indians, Africans, and Europeans. Deathways thus offer an unmatched way to understand the colonial encounter from the participants’ perspectives.

The process of urban deindustrialization has been long and uneven. Even the terms “deindustrial” and “postindustrial” are contested; most cities continue to host manufacturing on some scale. After World War II, however, cities that depended on manufacturing for their lifeblood increasingly diversified their economies in the face of larger global, political, and demographic transformations. Manufacturing centers in New England, the Mid Atlantic, and the Midwest United States were soon identified as belonging to “the American Rust Belt.” Steel manufacturers, automakers, and other industrial behemoths that were once mainstays of city life closed their doors as factories and workers followed economic and social incentives to leave urban cores for the suburbs, the South, or foreign countries. Remaining industrial production became increasingly automated, resulting in significant declines in the number of factory jobs. Metropolitan officials faced with declining populations and tax bases responded by adapting their assets—in terms of workforce, location, or culture—to new economies, including warehousing and distribution, finance, health care, tourism, leisure industries like casinos, and privatized enterprises such as prisons. Faced with declining federal funding for renewal, they focused on leveraging private investment for redevelopment. Deindustrializing cities marketed themselves as destinations with convention centers, stadiums, and festival marketplaces, seeking to lure visitors and a “creative class” of new residents. While some postindustrial cities became success stories of reinvention, others struggled. They entertained options to “rightsize” by shrinking their municipal footprints, adapted vacant lots for urban agriculture, or attracted voyeurs to gaze at their industrial ruins. Whether industrial cities faced a slow transformation or the shock of multiple factory closures within a few years, the impact of these economic shifts and urban planning interventions both amplified old inequalities and created new ones.
The history of dockworkers in America is as fascinating and important as it is unfamiliar. Those who worked along the shore loading and unloading ships played an invaluable role in an industry central to both the U.S. and global economies as well as the making of the nation. For centuries, their work remained largely the same, involving brute manual labor in gangs; starting in the 1960s, however, their work was entirely remade due to technological transformation. Dockworkers possess a long history of militancy, resulting in dramatic improvements in their economic and workplace conditions. Today, nearly all are unionists, but dockworkers in ports along the Atlantic and Gulf coasts belong to the International Longshoremen’s Association (ILA), while the International Longshore and Warehouse Union (ILWU) represents them in Pacific Coast ports as well as in Hawaii and Alaska (along with British Columbia and Panama). In the mid-1930s, the ILA and ILWU became bitter rivals and remain so. This feud, which has cooled slightly since its outset, can be explained by differences in leadership, ideology, and tactics, with the ILA more craft-based, “patriotic,” and mainstream and the ILWU quite left wing, especially during its first few decades, and committed to fighting for racial equality. The existence of two unions complicates this story; in most countries, dockworkers belong to a single union. Similarly, America’s massive economy and physical size means that there are literally dozens of ports (again, unlike many other countries), making generalizations harder. Unfortunately, popular culture depictions of dockworkers inculcate unfair and incorrect notions that all dockworkers are involved with organized crime. Nevertheless, due to decades of militancy, strikes, and unionism, dockworkers in 21st-century America are—while far fewer in number—very well paid and still do important work, literally making world trade possible in an era when 90 percent of goods move by ship for at least part of their journey to market.
Domestic work was, until 1940, the largest category of women’s paid labor. Despite the number of women who performed domestic labor for pay, the wages and working conditions were often poor. Workers labored long hours for low pay and were largely left out of state labor regulations. The association of domestic work with women’s traditional household labor, defined as a “labor of love” rather than as real work, and its centrality to southern slavery, have contributed to its low status. As a result, domestic work has long been structured by class, racial, and gendered hierarchies. Nevertheless, domestic workers have time and again done their best to resist these conditions. Although traditional collective bargaining techniques did not always translate to the domestic labor market, workers found various collective and individual methods to insist on higher wages and demand occupational respect, ranging from quitting to “pan-toting” to forming unions.
The use of illicit drugs in US cities led to the development of important subcultures with shared practices, codes, discourses, and values. From the 19th century onward, American city dwellers have indulged in opiates, cocaine, amphetamines, cannabis, lysergic acid diethylamide (LSD), crack, and 3,4-Methylenedioxymethamphetamine (also known as MDMA or ecstasy). The population density of metropolitan America contributed to the spread of substance use and the rise of communities that centered their lives on drug consumption. In the history of urban drug use, opiates have outlasted all the other drugs and have naturally attracted the bulk of scholarly attention.
The nature and identity of these illicit subcultures usually depended on the pharmacology of the drugs and the setting in which they were used. Addictive substances like heroin and amphetamines certainly led to the rise of crime in certain urban areas, but by the same token many urban Americans managed to integrate their addiction into their everyday lives. The more complex pharmacology of psychedelic drugs like LSD in turn gave birth to rich subcultures that resist easy classifications. Most drugs began their careers as medical marvels that were accepted as the product of modernity and often used by the middle class or medical practitioners. Race, age, and class prejudice, and the association of drugs with visible subcultures perceived to pose a threat to the moral fabric of society can partly explain their subsequent bans.

Americans almost universally agree on the importance of education to the success of individuals and the strength of the nation. Yet they have long differed over the proper mission of government in overseeing their schools. Before 1945, these debates largely occurred at the local and state levels. Since 1945, as education has become an increasingly national and international concern, the federal government has played a larger role in the nation’s schools. As Americans gradually have come to accept a greater federal presence in elementary and secondary schools, however, members of Congress and presidents from both major parties have continued to argue over the scope and substance of the federal role. From 1945 to 1965, these arguments centered on the quest for equity between rich and poor public school pupils and between public and nonpublic school students. From 1965 to 1989, national lawmakers devoted much of their attention to the goal of excellence in public education. From 1989 to the present, they have quarreled over how best to attain equity and excellence at the same time.

The Ellis Island Immigration Station, located in New York Harbor, opened in 1892 and closed in 1954. During peak years from the 1890s until the 1920s, the station processed an estimated twelve million immigrants. Roughly 75 percent of all immigrants arriving in America during this period passed through Ellis Island. The station was run by the federal Immigration Service and represented a new era of federal control over immigration. Officials at Ellis Island were tasked with regulating the flow of immigration by enforcing a growing body of federal laws that barred various categories of “undesirable” immigrants. As the number of immigrants coming to America increased, so did the size of the inspection facility. In 1907, Ellis Island processed more than one million immigrants. The quota laws of the 1920s slowed immigration considerably and the rise of the visa system meant that Ellis Island no longer served as the primary immigrant inspection facility. For the next three decades, Ellis Island mostly served as a detention center for those ordered deported from the country.
After Ellis Island closed in 1954, the facility fell into disrepair. During a period of low immigration and a national emphasis on assimilation, the immigrant inspection station was forgotten by most Americans. With a revival of interest in ethnicity in the 1970s, Ellis Island attracted more attention, especially from the descendants of immigrants who entered the country through its doors. In the 1980s, large-scale fundraising for the restoration of the neighboring Statue of Liberty led to a similar effort to restore part of Ellis Island. In 1990, the Main Building was reopened to the public as an immigration museum under the National Park Service. Ellis Island has evolved into an iconic national monument with deep meaning for the descendants of the immigrants who arrived there, as well as a contested symbol to other Americans grappling with the realities of contemporary immigration.
Employers began organizing with one another to reduce the power of organized labor in the late 19th and early 20th centuries. Irritated by strikes, boycotts, and unions’ desire to achieve exclusive bargaining rights, employers demanded the right to establish open shops, workplaces that promoted individualism over collectivism. Rather than recognize closed or union shops, employers demanded the right to hire and fire whomever they wanted, irrespective of union status. They established an open-shop movement, which was led by local, national, and trade-based employers. Some formed more inclusive “citizens’ associations,” which included clergymen, lawyers, judges, academics, and employers. Throughout the 20th century’s first three decades, this movement succeeded in busting unions, breaking strikes, and blacklisting labor activists. It united large numbers of employers and was mostly successful. The movement faced its biggest challenges in the 1930s, when a liberal political climate legitimized unions and collective bargaining. But employers never stopped organizing and fighting, and they continued to undermine the labor movement in the following decades by invoking the phrase “right-to-work,” insisting that individual laborers must enjoy freedom from so-called union bosses and compulsory unionism. Numerous states, responding to pressure from organized employers, begin passing “right-to-work” laws, which made union organizing more difficult because workers were not obligated to join unions or pay their “fair share” of dues to them. The multi-decade employer-led anti-union movement succeeded in fighting organized labor at the point of production, in politics, and in public relations.
Energy systems have played a significant role in U.S. history; some scholars claim that they have determined a number of other developments. From the colonial period to the present, Americans have shifted from depending largely on wood and their own bodies, as well as the labor of draft animals; to harnessing water power; to building steam engines; to extracting fossil fuels—first coal and then oil; to distributing electrical power through a grid. Each shift has been accompanied by a number of other striking changes, especially in the modern period associated with fossil fuels. By the late 19th century, in part thanks to new energy systems, Americans were embracing industrialization, urbanization, consumerism, and, in a common contemporary phrase, “the annihilation of space and time.” Today, in the era of climate change, the focus tends to be on the production or supply side of energy systems, but a historical perspective reminds us to consider the consumption or demand side as well. Just as important as the striking of oil in Beaumont, Texas, in 1901, was the development of new assumptions about how much energy people needed to sustain their lives and how much work they could be expected to do. Clearly, Americans are still grappling with the question of whether their society’s heavy investment in coal- and petroleum-based energy systems has been worthwhile.

The Enlightenment, a complex cultural phenomenon that lasted approximately from the late seventeenth century until the early nineteenth century, contained a dynamic mix of contrary beliefs and epistemologies. Its intellectual coherence arguably came from its distinctive historical sensibility, which was rooted in the notion that advances in the natural sciences had gifted humankind with an exceptional opportunity in the eighteenth century for self-improvement and societal progress. That unifying historical outlook was flexible and adaptable. Consequently, many aspects of the Enlightenment were left open to negotiation at local and transnational levels. They were debated by the philosophes who met in Europe’s coffeehouses, salons, and scientific societies. Equally, they were contested outside of Europe through innumerable cross-cultural exchanges as well as via long-distance intellectual interactions.
America—whether it is understood expansively as the two full continents and neighboring islands within the Western Hemisphere or, in a more limited way, as the territory that now constitutes the United States—played an especially prominent role in the Enlightenment. The New World’s abundance of plants, animals, and indigenous peoples fascinated early modern natural historians and social theorists, stimulated scientific activity, and challenged traditional beliefs. By the eighteenth century, the Western Hemisphere was an important site for empirical science and also for the intersection of different cultures of knowledge. At the same time, European conceptions of the New World as an undeveloped region inhabited by primitive savages problematized Enlightenment theories of universal progress. Comparisons of Native Americans to Africans, Asians, and Europeans led to speculation about the existence of separate human species or races. Similarly, the prevalence and profitability of American slavery fueled new and increasingly scientific conceptions of race. Eighteenth-century analyses of human differences complicated contemporary assertions that all men possessed basic natural rights. Toward the end of the eighteenth century, the American Revolution focused international attention on man’s innate entitlement to life, liberty, and happiness. Yet, in a manner that typified the contradictions and paradoxes of the Enlightenment, the founders of the United States opted to preserve slavery and social inequality after winning political freedom from Britain.

By the late 19th century, American cities like Chicago and New York were marvels of the industrializing world. The shock urbanization of the previous quarter century, however, brought on a host of environmental problems. Skies were acrid with coal smoke, and streams ran fetid with raw sewage. Disease outbreaks were as common as parks and green space was rare. In response to these hazards, particular groups of urban residents responded to them with a series of activist movements to reform public and private policies and practices, from the 1890s until the end of the 20th century. Those environmental burdens were never felt equally, with the working class, poor, immigrants, and minorities bearing an overwhelming share of the city’s toxic load. By the 1930s, many of the Progressive era reform efforts were finally bearing fruit. Air pollution was regulated, access to clean water improved, and even America’s smallest cities built robust networks of urban parks. But despite this invigoration of the public sphere, after World War II, for many the solution to the challenges of a dense modern city was a private choice: suburbanization. Rather than continue to work to reform and reimagine the city, they chose to leave it, retreating to the verdant (and pollution free) greenfields at the city’s edge. These moves, encouraged and subsidized by local and federal policies, provided healthier environments for the mostly white, middle-class suburbanites, but created a new set of environmental problems for the poor, working-class, and minority residents they left behind. Drained of resources and capital, cities struggled to maintain aging infrastructure and regulate remaining industry and then exacerbated problems with destructive urban renewal and highway construction projects. These remaining urban residents responded with a dynamic series of activist movements that emerged out of the social and community activism of the 1960s and presaged the contemporary environmental justice movement.
The development of nuclear technology had a profound influence on the global environment following the Second World War, with ramifications for scientific research, the modern environmental movement, and conceptualizations of pollution more broadly. Government sponsorship of studies on nuclear fallout and waste dramatically reconfigured the field of ecology, leading to the widespread adoption of the ecosystem concept and new understandings of food webs as well as biogeochemical cycles. These scientific endeavors of the atomic age came to play a key role in the formation of environmental research to address a variety of pollution problems in industrialized countries. Concern about invisible radiation served as a foundation for new ways of thinking about chemical risks for activists like Rachel Carson and Barry Commoner as well as many scientists, government officials, and the broader public. Their reservations were not unwarranted, as nuclear weapons and waste resulted in radioactive contamination of the environment around nuclear-testing sites and especially fuel-production facilities. Scholars date the start of the “Anthropocene” period, during which human activity began to have substantial effects on the environment, variously from the beginning of human farming roughly 8,000 years ago to the emergence of industrialism in the 19th century. But all agree that the advent of nuclear weapons and power has dramatically changed the potential for environmental alterations. Our ongoing attempts to harness the benefits of the atomic age while lessening its negative impacts will need to confront the substantial environmental and public-health issues that have plagued nuclear technology since its inception.

Few developments in human history match the demographic consequences of the arrival of Europeans in the Americas. Between 1500 and 1900 the human populations of the Americas were traBnsformed. Countless American Indians died as Europeans established themselves, and imported Africans as slaves, in the Americas. Much of the mortality came from epidemics that swept through Indian country. The historical record is full of dramatic stories of smallpox, measles, influenza, and acute contagious diseases striking American Indian communities, causing untold suffering and facilitating European conquest. Some scholars have gone so far as to invoke the irresistible power of natural selection to explain what happened. They argue that the long isolation of Native Americans from other human populations left them uniquely susceptible to the Eurasian pathogens that accompanied European explorers and settlers; nothing could have been done to prevent the inevitable decimation of American Indians. The reality, however, is more complex. Scientists have not found convincing evidence that American Indians had a genetic susceptibility to infectious diseases. Meanwhile, it is clear that the conditions of life before and after colonization could have left Indians vulnerable to a host of diseases. Many American populations had been struggling to subsist, with declining populations, before Europeans arrived; the chaos, warfare, and demoralization that accompanied colonization made things worse. Seen from this perspective, the devastating mortality was not the result of the forces of evolution and natural selection but rather stemmed from social, economic, and political forces at work during encounter and colonization. Getting the story correct is essential. American Indians in the United States, and indigenous populations worldwide, still suffer dire health inequalities. Although smallpox is gone and many of the old infections are well controlled, new diseases have risen to prominence, especially heart disease, diabetes, cancer, substance abuse, and mental illness. The stories we tell about the history of epidemics in Indian country influence the policies we pursue to alleviate them today.
Ethnicity is a concept employed to understand the social, cultural, and political processes whereby immigrants and their children cease to be “foreign” and yet retain practices and networks that connect them, at least imaginatively, with places of origin. From an early juncture in American history, ethnic neighborhoods were an important part of such processes. Magnets for new arrivals, city neighborhoods both emerged from and reinforced connections among people of common origins. Among the first notable immigrant neighborhoods in American cities were those composed of people from the German-speaking states of Europe. In the second half of the 19th century, American cities grew rapidly and millions of immigrants arrived to the country from a wider array of origins; neighborhoods such as the New York’s Jewish Lower East Side and San Francisco’s Chinatown supported dense and institutionally complex ethnic networks. In the middle decades of the 20th century, immigration waned as a result of legislative restriction, economic depression, and war. Many former immigrant neighborhoods emptied of residents as cities divided along racial lines and “white ethnics” dispersed to the suburbs. However, some ethnic enclaves endured, while others emerged after the resumption of mass immigration in the 1960s. By the turn of the 21st century ethnic neighborhoods were once again an important facet of American urban life, although they took new forms within the reconfigured geography and economy of a suburbanized nation.

The Sacramento Delta is an agricultural region in northern California with deep historic significance for Asian Americans. Asian American laborers were instrumental to the development of Sacramento Delta, transforming the swampy peat bog into one of the richest agricultural areas in California. Beginning in the mid-19th century, Chinese laborers constructed levees, dikes, and ditches along the Sacramento and San Joaquin Rivers before breaking the fertile soil to grow fruit and vegetables including pears and asparagus. Asian Americans continued a permanent and transient presence in the Sacramento Delta on farms as migrant farm laborers, permanent farmworkers, and overseers, and in the small delta towns such as Isleton that emerged as merchants, restaurant operators, boardinghouse operators, and other business owners catering to the local community.
