Final answer:
The Roosevelt Corollary allowed the United States to intervene in Latin American countries to protect its own interests, leading to increased American involvement in the region. It resulted in military and economic interventions in countries like the Dominican Republic, Cuba, and Nicaragua.
Step-by-step explanation:
The Roosevelt Corollary was an extension of the Monroe Doctrine issued by President Theodore Roosevelt in 1904. It stated that the United States had the right to intervene in the affairs of Latin American countries to protect its own interests. The corollary had significant impacts on Latin America, as it led to increased American involvement in the region, both politically and economically. The United States used this policy to justify military interventions and interventions in economic matters in countries such as the Dominican Republic, Cuba, and Nicaragua.
