The Foraker Act, , officially known as the Organic Act of 1900, is a United States federal law that established civilian (albeit limited popular) government on the island of Puerto Rico, which had recently become a possession of the United States as a result of the Spanish–American War. Section VII of the Foraker Act also established Puerto Rican citizenship. President William McKinley signed the act on April 12, 1900 and it became known as the Foraker Act after its sponsor, Ohio Senator Joseph B. Foraker. Its main author has been identified as Secretary of War Elihu Root.
