By serving travelers and commerce, roads and streets unite people and foster economic growth. But as they develop, roads and streets also disrupt old patterns, upset balances of power, and isolate some as they serve others. The consequent disagreements leave historical records documenting social struggles that might otherwise be overlooked. For long-distance travel in America before the middle of the 20th century, roads were generally poor alternatives, resorted to when superior means of travel, such as river and coastal vessels, canal boats, or railroads were unavailable. Most roads were unpaved, unmarked, and vulnerable to the effects of weather. Before the railroads, for travelers willing to pay the toll, rare turnpikes and plank roads could be much better. Even in towns, unpaved streets were common until the late 19th century, and persisted into the 20th. In the late 19th century, rapid urban growth, rural free delivery of the mails, and finally the proliferation of electric railways and bicycling contributed to growing pressure for better roads and streets. After 1910, the spread of the automobile accelerated the trend, but only with great controversy, especially in cities. Partly in response to the controversy, advocates of the automobile organized to promote state and county motor highways funded substantially by gasoline taxes; such roads were intended primarily for motor vehicles. In the 1950s, massive federal funds accelerated the trend; by then, motor vehicles were the primary transportation mode for both long and short distances. The consequences have been controversial, and alternatives have been attracting growing interest.
Irish and American histories are intertwined as a result of migration, mercantile and economic connections, and diplomatic pressures from governments and nonstate actors. The two fledgling nations were brought together by their shared histories of British colonialism, but America’s growth as an imperial power complicated any natural allegiances that were invoked across the centuries. Since the beginnings of that relationship in 1607 with the arrival of Irish migrants in America (both voluntary and forced) and the building of a transatlantic linen trade, the meaning of “Irish” has fluctuated in America, mirroring changes in both migrant patterns and international politics. The 19th century saw Ireland enter into Anglo-American diplomacy on both sides of the Atlantic, while the 20th century saw Ireland emerge from Britain’s shadow with the establishment of separate diplomatic connections between the United States and Ireland. American recognition of the newly independent Irish Free State was vital for Irish politicians on the world stage; however the Free State’s increasingly isolationist policies during the 1930s to 1950s alienated its American allies. The final decade of the century, however, brought America and Ireland (including both Northern Ireland and the Republic of Ireland) closer than ever before. Throughout their histories, the Irish diasporas—both Protestant and Catholic—in America have played vital roles as pressure groups and fundraisers. The history of American–Irish relations therefore brings together governmental and nonstate organizations and unites political, diplomatic, social, cultural, and economic histories which are still relevant today.

Since the founding of the United States of America, coinciding with the height of the Atlantic slave trade, U.S. officials have based their relations with West Africa primarily on economic interests. Initially, these interests were established on the backs of slaves, as the Southern plantation economy quickly vaulted the United States to prominence in the Atlantic world. After the U.S. abolition of the slave trade in 1808, however, American relations with West Africa focused on the establishment of the American colony of Liberia as a place of “return” for formerly enslaved persons. Following the turn to “legitimate commerce” in the Atlantic and the U.S. Civil War, the United States largely withdrew from large-scale interaction with West Africa. Liberia remained the notable exception, where prominent Pan-African leaders like Edward Blyden, W. E. B. DuBois, and Marcus Garvey helped foster cultural and intellectual ties between West Africa and the Diaspora in the early 1900s. These ties to Liberia were deepened in the 1920s when Firestone Rubber Corporation of Akron, Ohio established a long-term lease to harvest rubber. World War II marked a significant increase in American presence and influence in West Africa. Still focused on Liberia, the war years saw the construction of infrastructure that would prove essential to Allied war efforts and to American security interests during the Cold War. After 1945, the United States competed with the Soviet Union in West Africa for influence and access to important economic and national security resources as African nations ejected colonial regimes across most of the continent. West African independence quickly demonstrated a turn from nationalism to ethnic nationalism, as civil wars engulfed several countries in the postcolonial, and particularly the post-Cold War, era. After a decade of withdrawal, American interest in West Africa revived with the need for alternative sources of petroleum and concerns about transnational terrorism following the attacks of September 11, 2001.
