american continued interest in latin america came from an earlier policy known as
Latin America–United States relations The Mexican Revolution started in 1911; it alarmed American business interests that had invested in Mexican mines and railways. The United States involvement in the Mexican Revolution, include, among other violations of sovereignty, the ambassadorial backing of a coup and assassination of President Francisco I. Madero and the military occupation of Veracruz. Large numbers of Mexicans fled the war-torn revolution into the southwestern United States. Meanwhile, the United States increasingly replaced Britain as the major trade partner and financier throughout Latin America. The US adopted a â€œGood Neighbor Policy" in the 1930s, which meant friendly trade relations would continue regardless of political conditions or dictatorships. United States signed up the major countries as allies against Germany and Japan in World War II. However, some countries like Argentina, Chile, Ecuador, Paraguay, Uruguay and Venezuela only joined the Allied side in 1945. The era of the Good Neighbor Policy ended with the ramp-up of the Cold War in 1945, as the United States felt there was a greater need to protect the western hemisphere from Soviet Union influence and a potential rise of communism. These changes conflicted with the Good Neighbor Policy's fundamental principle of non-intervention and led to a new wave of US involvement in Latin American affairs.
Spanish colonization of the Americas Beginning with the 1492 arrival of Christopher Columbus in the Caribbean and continuing control of vast territory for over three centuries, the Spanish Empire would expand across the Caribbean Islands, half of South America, most of Central America and much of North America (including present day Mexico, Florida and the Southwestern and Pacific Coastal regions of the United States). It is estimated that during the colonial period (1492–1832), a total of 1.86 million Spaniards settled in the Americas and a further 3.5 million immigrated during the post-colonial era (1850–1950); the estimate is 250,000 in the 16th century, and most during the 18th century as immigration was encouraged by the new Bourbon Dynasty.
