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.
From 1800 to the present, US troops have intervened thousands of times in Latin America and have occupied its countries on dozens of occasions. Interventions were short-term and superficial, while occupations lasted longer and controlled local governments. The causes of these troop landings reflected the United States’ motivations as it expanded from a strong, large republic into first a continental and then an overseas empire at the expense of its smaller, weaker neighbors. Those motivations included colonial land hunger, cultural chauvinism, the exploitation of resources, the search for markets abroad, competition against other great powers, political reformism, global ideological struggle, and the perception that US domestic problems originated in Latin America. US troops undertook almost all these interventions and occupations, although private groups sometimes joined. The major periods were the expansion of the continental republic from 1811 to 1897, the war in Cuba and the apex of occupations (1898–1933), the Good Neighbor years (1934–1953), the Cold War (1954–1990), and the post-Cold War period (1991–2018 and ongoing). Scholars of these events have become increasingly critical and diverse, not only seeing them often as unnecessary brutal failures but also foregrounding extra-military aspects of these episodes, such as economics, race, and gender.
