Lewis Cass

Lewis Cass (October 9, 1782 – June 17, 1866) was a United States Army officer and politician. He represented Michigan in the United States Senate and served in the Cabinets of two U.S. Presidents, Andrew Jackson and James Buchanan. He was also the 1848 Democratic presidential nominee. A slave owner himself, he was a leading spokesman for the doctrine of popular sovereignty, which at the time held the idea that people in each U.S state should have the right to decide whether to permit slavery as a matter of states' rights. 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 eventually co-founded 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 American tribes to open land for American settlement as part of a belief in "manifest destiny" 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, 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 for president at the 1848 Democratic National Convention precipitated a split in the party, as Cass's advocacy for popular sovereignty alienated the anti-slavery wing...
