After the American Civil War and Cuba's Ten Years' War, U.S. businessmen began monopolizing the devalued sugar markets in Cuba. In 1894, 90% of Cuba's total exports went to the United States, which also provided 40% of Cuba's imports. Cuba's total exports to the U.S. were almost twelve times larger than the export to her mother country, Spain. U.S. business interests indicated that while Spain still held political authority over Cuba, it was the US that held economic power over Cuba.
