Biography
Theodore Roosevelt (1858–1919) was the 26th President of the United States, serving from 1901 to 1909. He became president at age 42 — the youngest in history at the time — after the assassination of William McKinley, having previously served as Vice President, Governor of New York, and Assistant Secretary of the Navy. He gained national fame leading the "Rough Riders" cavalry unit during the Spanish-American War. As president, he was a progressive reformer known for trust-busting large monopolies, championing conservation (establishing national parks, forests, and monuments), and pursuing an assertive foreign policy summarized by his motto "speak softly and carry a big stick" — including overseeing construction of the Panama Canal. After leaving office, he ran for a third term in 1912 under the Progressive "Bull Moose" Party, splitting the Republican vote.
