imperialism is where an stronger country take over a weaker country
By the end of the 19th century, American sailors had long been familiar with the various Pacific islands. American businessmen involved in overseas trade saw Samoa as an important link in the South Pacific. Similar businessmen were also heavily involved in the sugar trade with Hawaii, and plantations owned by Americans began to exert heavy influence over the islands
Spain ceded the Philippines to the United States in 1898 under the terms of the Treaty of Paris. However, this marked the beginning of a brutal conflict between Filipino nationalists and the American military. The role of the U.S. in the Philippines was controversial, and many saw it as unabashed American imperialism. Those in favor of annexation feared another colonial power taking over the islands and threatening American economic concerns.
The United States acquired Puerto Rico as a spoil of victory in the Spanish-American War. Unlike the Philippines, annexation of Puerto Rico went much more smoothly. The U.S. viewed the territory not only as an important economic region, but it also sought to establish a key naval base on the island. The governing of Puerto Rico moved rapidly, and a civilian government was established in April 1900 under the Forsake law. The law essentially established the territory as subject to all U.S. federal laws, but it has yet to become a state.
Italy was another late entry into the imperialistic venture. Italy took control of Libya, Italian Somali land, and Eritrea, which is the north-most province of Ethiopia, near the Red Sea. Italy’s efforts to gain control of Ethiopia ended in bitter defeat.
