The Teller Amendment is the correct answer.
After the end of the Spanish-American War, Senator Henry Teller of Colorado introduced the Teller Amendment in 1898, that the United States conquered Cuba until 1902, and did not violate the Teller Amendment to annex the Island. And the U.S. would help Cuba to gain independence and then withdraw all its troops from the country. This amendment was a part of President Mckinley's to resolve the issues between U.S and Spain. The United States promised to allow Cuba to be administered by its people, after assisting them to gain some stability and smooth over the dispute with Spain.
One of the most important rules to the Native Americans was that land was to be used by tribes regardless of whether or not it was "worked" in the traditional European sense. This led to great conflict with the Europeans, who thought the Natives weren't entitled to the land if they did farm on it.
