Ann Arbor History

Ann Arbor was founded in 1824 by Elisha Walker Rumsey and John Allen, and the town was registered with Wayne County as Annarbour that year. The city was named for the men's wives, both named Ann, and for large stands of burr oak in the land purchased from the government for $800.

Ann Arbor became the seat of Washtenaw County three years later and it was incorporated as a village just six years later. The Ann Arbor Land Company set aside undeveloped land and offered it to Michigan as the site of the state capital, but the bid was lost to Lansing and the property instead became the site of the University of Michigan, which shaped the future of the city.

Ann Arbor saw strong growth in the 1880s with new immigrants from Poland, Russia, Italy and Greece joining the Irish, Germans, English and African-Americans already present. Ann Arbor eventually gained a reputation as a center for liberal politics during the 1960s and 1970s, particularly for the civil rights and anti-Vietnam War movements.
