01 / The Detroit story
The Detroit story
Lewis Cass came to Detroit as an Ohio militia officer in the War of 1812 and was among the troops surrendered with the town in 1812. After the American recapture, President Madison named him governor of Michigan Territory in 1813, and he ruled from Detroit until 1831. He negotiated a series of treaties under which Native nations ceded vast lands, opening Michigan to settlers, and led an 1820 expedition into the upper Great Lakes. As Andrew Jackson's secretary of war he carried out Indian removal. He then served Michigan as a U.S. senator, ran for president in 1848 on the doctrine of popular sovereignty over slavery, and was secretary of state under Buchanan until he resigned in 1860. A slave owner himself, he remains a contested figure. He died in Detroit in 1866 and is buried at Elmwood Cemetery.
