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.
