Why did US send troops to latin America in the 1900s?

In the 1900s, the United States sent troops to Latin America primarily to protect its economic interests and maintain regional stability. This intervention was often justified under the Monroe Doctrine, which aimed to prevent European influence in the Western Hemisphere. Key events, such as the construction of the Panama Canal and the desire to curb German and British influence, prompted military actions in countries like Cuba, Nicaragua, and Haiti. The U.S. sought to establish itself as a dominant power in the region through a policy known as "Big Stick Diplomacy."
