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.
