South America had many unpaid debts and foreign powers, mainly Europe, began to make their appearance in the Southern America landscape. President Roosevelt did not want Europe in Mexico because he feared Europe would move into America. So he changed the Monroe Doctrine to better fit the needs of America. His change was called the Roosevelt Corollary and allowed America to intervene with Latin America problems. In Theodore Roosevelt's Annual Message to Congress, he said the Roosevelt Corollary was to help spread democracy and keep neighboring nations efficient. This is very different from the past because the Monroe Doctrine was to protect America and the Roosevelt Corollary was to direct Latin America. Though these were new changes, there were some links to the past. The conquered people were still treated poorly. In the Supreme Court Decision of Downes v. Bidwell, one of the Insular Cases, the Supreme Court ruled that even though a new territory might make the inhabitants American citizens, it did not guarantee full constitutional rights. Just as in the past, Native Americans and African-Americans were still treated poorly and some were even scattered to camps, as they had been during the time of settling the West. The Filipinos fate was also decided by the basis of American desires, just like the Native Americans years before. In the Platform of the American Anti-Imperialist League, the Filipinos stress how much they hate the forcing of American plans because America was seeking to destroy the Filipinos traditions. Yet again, one might notice that people are being taken advantage of without much of their consent, just like the past with the Natives and African Americans. Politics linked late nineteenth-century and early twentieth-century Untied States to the past and at the same time made it a departure.
From the late nineteenth-century and early twentieth-century, the United States economic plans showed less of a continuation of past expansion, and more of a departure from the past.
