As a result of the Spanish-American War, Spain ceded much of its empire to the United States, including Guam, the Ladrones (now the Mariana Islands), the Philippines, and Puerto Rico. Spain also relinquished its claim to Cuba, which was ruled by a U.S. military government until 1902. Congress subsequently annexed Hawaii, Wake Island, and part of the Samoa Islands. By the start of the 20th century the Navy had helped deliver to the United States a sprawling empire in the Pacific, and helped ensure access to new markets for the country’s exports. In 1907 President Theodore Roosevelt sent about half of the U.S. Navy on a worldwide “practice cruise” to assert the country’s military dominance. The tour, the first of its kind for the United States, was particularly directed at Japan. The Japanese greeted the visiting American sailors warmly but then began improving their own naval fleet. Known as the Great White Fleet, the cruise also helped win congressional support for increased funding for the Navy.
