From the period of imperial conquest and competition, the Caribbean coast of Central America has served as an interstitial space: between British and Spanish rule; between foreign corporate control and national inclusion; mestizo, black, and indigenous. Running from Guatemala in the north through Honduras, Nicaragua, Costa Rica, and Panama in the south, “la Costa” has functioned as a contested terrain imbued with economic import, ethnic difference, and symbolic power. The coastal zones were transformed in the 20th century through the construction of railroads and later highways, large-scale foreign immigration, the spread of states’ bureaucratic agents, and internal migrants, as well as transnational projects such as the Panama Canal and the United Fruit Company’s integrated banana plantation empire.
The coastal region’s inaccessible terrain, large communities of lowland indigenous people, and vast numbers of Afro-Caribbean migrants from islands such as Jamaica markedly differentiated these lowlands from the wider Central American republics. From indigenous groups such as the Rama, Mayangna-Sumu, Kuna, Guaymí, and Bribri, to the Afro-indigenous Garifuna and Miskitu, and the English-speaking black Creoles and Afro-Antilleans, the region has enjoyed great ethnic diversity compared to the nominally mestizo republics of which it has formed part. Finally, ladino (non-indigenous) or mestizo (mixed-race) campesino migrants from the Pacific or Central regions of the isthmus arrived in large numbers throughout the 20th century. Racism, ethnic exclusion, and marginalization were often the response of national states toward these coastal populations. In some contexts, tensions between and among ethnic groups over land and natural resources, as well as between national states and local autonomy, flared into violent conflict. Elsewhere in Central America, the Caribbean coast’s position in national political development permitted a gradual meshing of national and regional cultures during the second half of the 20th century.
U.S. foreign policy toward Latin America in the 19th century initially focused on excluding or limiting the military and economic influence of European powers, territorial expansion, and encouraging American commerce. These objectives were expressed in the No Transfer Principle (1811) and the Monroe Doctrine (1823). American policy was unilateralist (not isolationist); it gradually became more aggressive and interventionist as the idea of Manifest Destiny contributed to wars and military conflicts against indigenous peoples, France, Britain, Spain, and Mexico in the Western Hemisphere. Expansionist sentiments and U.S. domestic politics inspired annexationist impulses and filibuster expeditions to Mexico, Cuba, and parts of Central America. Civil war in the United States put a temporary halt to interventionism and imperial dreams in Latin America. From the 1870s until the end of the century, U.S. policy intensified efforts to establish political and military hegemony in the Western Hemisphere, including periodic naval interventions in the Caribbean and Central America, reaching even to Brazil in the 1890s. By the end of the century Secretary of State Richard Olney added the Olney Corollary to the Monroe Doctrine (“Today the United States is practically sovereign on this continent and its fiat is law upon the subjects to which it confines its interposition . . .”), and President Theodore Roosevelt contributed his own corollary in 1904 (“in the Western Hemisphere the adherence of the United States to the Monroe Doctrine may force the United States, however reluctantly, in flagrant cases of wrongdoing or impotence, to exercise an international police power”). American policy toward Latin America, at the turn of the century, explicitly justified unilateral intervention, military occupation, and transformation of sovereign states into political and economic protectorates in order to defend U.S. economic interests and an expanding concept of national security.
