Puerto Ricans expel United States Navy from Culebra Island, 1970-1974
In 1970, Puerto Rico was a non-sovereign territory of the United States. Its residents were U.S. citizens but could not vote in presidential elections, nor did they have political representation in the U.S. Congress, although they could serve and be drafted in the U.S. armed forces. At the beginning of the 20th century, the U.S. Navy eliminated the principal town on the island of Culebra and evicted its residents so that a marine base could be built. In 1941, President Roosevelt claimed exclusive rights to the air space above Culebra as well as a three-mile wide radius around the island.
