In what country did the U.S. intervene when a financial crisis hit in 1905 prompting President Roosevelt to declare the island a financial protectorate.

That country is the Dominican Republic.

Under pressure from Washington, the Dominican Republic´s government asked the United States to intervene in the country to restore order in finances in 1905. In an executive order, the US issued a guarantee that it would respect Dominican territorial  integrity and that it would assume custom house collection, using 55% of receipts to pay outstanding obligations.

The year before, president Ted Roosevelt had formulated the policy later known as the Roosevelt Corollary to the Monroe Doctrine. It said that the US would not allow European powers to collect debts from Latin American and Caribbean nations by force.

One magor change is that Portuguese spread vastly throughout the continent of South America.
