Theodore Roosevelt Born in New York City
Summary
Theodore Roosevelt was born on October 27, 1858, in New York City. Frequently ill with asthma as a child, he developed an intense interest in natural history and physical activity. Roosevelt graduated from Harvard, entered New York politics, and later served in federal civil service, as New York City police commissioner, assistant secretary of the Navy, and governor of New York. During the Spanish-American War, he gained national attention as a leader of the volunteer cavalry unit known as the Rough Riders. Roosevelt became vice president in 1901 and succeeded to the presidency after William McKinley's assassination. As the twenty-sixth president, he promoted stronger federal regulation of corporations, consumer protections, conservation, and a more active international role for the United States. After leaving office, he broke with his successor William Howard Taft and ran for president as the Progressive Party candidate in 1912, surviving an assassination attempt during that campaign.
Why It Matters
Roosevelt expanded expectations of presidential leadership and federal responsibility during the Progressive Era. His administration pursued antitrust enforcement, railroad regulation, food and drug protections, and extensive conservation initiatives. He also strengthened American naval and diplomatic power abroad. His 1912 Progressive campaign influenced later reform politics, while his energetic approach to executive authority helped shape the modern presidency.
