that while Spain still held political authority over Cuba, it was the U.S. that held economic power over Cuba. The U.S. became interested in a trans-isthmus canal in either Nicaragua or Panama and realized the need for naval protection. Captain Alfred Thayer Mahan was an exceptionally influential theorist; his ideas were much admired by future 26th President Theodore Roosevelt, as the U.S. rapidly built a powerful naval fleet of steel warships in the 1880s and 1890s. Roosevelt served as Assistant Secretary of the Navy in 1897–1898 and was an aggressive supporter of an American war with Spain over Cuban interests. Meanwhile, the "Cuba Libre" movement, led by Cuban intellectual José Martí until he died in 1895, had established offices in Florida. The face of the Cuban revolution in the U.S. was the "Cuban Junta", under the leadership of Tomás Estrada Palma, who in 1902 became Cuba's first president. The Junta dealt with leading newspapers and Washington officials and held fund-raising events across the U.S. It funded and smuggled weapons. It mounted an extensive propaganda campaign that generated enormous popular support in the U.S. in favor of the Cubans. Protestant churches and most Democrats were supportive, but business interests called on Washington to negotiate a settlement and avoid war. Cuba attracted enormous American attention, but almost no discussion involved the other Spanish colonies of Puerto Rico, also in the Caribbean, or of the Philippines or Guam. Historians note that there was no popular demand in the United States for an overseas colonial empire.

Neither the fighting nor the reforms in the Pact of Zanjón (February 1878) quelled the desire of some revolutionaries for wider autonomy and, ultimately, independence. One such revolutionary, José Martí, continued to promote Cuban financial and political freedom in exile. In early 1895, after years of organizing, Martí launched a three-pronged invasion of the island. The plan called for one group from Santo Domingo in the Dominican Republic led by Máximo Gómez, one group from Costa Rica led by Antonio Maceo Grajales, and another from the United States (preemptively thwarted by U.S. officials in Florida) to land in different places on the island and provoke an uprising. While their call for revolution, the grito de Baire, was successful,
