The US's foreign policy toward Latin American shifted considerably during the nineteenth century. It initially focused on limiting the military and economic influence of traditional European powers. These objectives were clearly expressed in documents like the No Transfer Principle of 1811 and eventually the Monroe Doctrine of 1823. The US approach during this time was akin to their attempts to contain the spread of communism in the Cold War.
As the nineteenth century moved towards the twentieth, US foreign policy in Latin America became more aggressive. The US was more inclined to exercise its power and intervene in conflicts across the continents. The US based these interventions on the idea of Manifest Destiny—the belief that US expansion throughout the American continents was not only justified but also inevitable. This was a time of naval interventions in multiple Caribbean and Central American countries. The US even extended its reach all the way to Brazil in the 1890s.
This expansion is a type of globalization. More specifically, it is a prime example of both political and economic globalization. The US believed it had the right to push out hostile regimes in Central and South American nations and replace them with government more friendly to US interests. This was done for both political and economic reasons. Friendly government abroad were more likely to trade with the US and to give the US more favorable deals.
