Researching Lewis Cass

Born in Exeter, New Hampshire, he attended Phillips Exeter Academy before establishing a legal practice in Zanesville, Ohio. After serving in the Ohio House of Representatives, he was appointed as a U.S. Marshal. Cass also joined the Freemasons and would eventually co-found the Grand Lodge of Michigan. He fought at the Battle of the Thames in the War of 1812 and was appointed to govern Michigan Territory in 1813. He negotiated treaties with Native Americans to open land for American settlement and led a survey expedition into the northwest part of the territory.

Cass resigned as governor in 1831 to accept appointment as Secretary of War under Andrew Jackson. As Secretary of War, he helped implement Jackson’s policy of Indian removal. After serving as ambassador to France from 1836 to 1842, he unsuccessfully sought the presidential nomination at the 1844 Democratic National Convention; a deadlock between supporters of Cass and former President Martin Van Buren ended with the nomination of James K. Polk. In 1845, the Michigan Legislature elected Cass to the Senate, where he served until 1848. Cass’s nomination at the 1848 Democratic National Convention precipitated a split in the party, as Cass's advocacy for popular sovereignty alienated the anti-slavery wing of the party. Van Buren led the Free Soil Party's presidential ticket and appealed to many anti-slavery Democrats, possibly contributing to the victory of Whig nominee Zachary Taylor.

Cass returned to the Senate in 1849 and continued to serve until 1857 when he accepted appointment as the Secretary of State. He unsuccessfully sought to buy land from Mexico and sympathized with American filibusters in Latin America. Cass resigned from the Cabinet in December 1860 in protest of Buchanan's handling of the threatened secession of several Southern states. Since his death in 1866, he has been commemorated in various ways, including with a statue in the National Statuary Hall.
