Adrian is a city in the U.S. state of Michigan and the county seat of Lenawee County. The population was 21,133 at the 2010 census. Adrian lies in Michigan's 7th congressional district.
Adrian was founded on June 18, 1826 by Addison Comstock. The original name for the village was Logan, but was changed soon after to Adrian, perhaps in reference to the Roman emperor Hadrian. The first operating railroad in Michigan was a horse-drawn train running between Adrian and Toledo in 1836. Adrian grew quickly, with the sixth largest population in the state when Michigan was admitted to the Union in 1837, and the third largest population in the state by 1860.
Evangelical and Hicksite Quakers in Southeast Michigan founded the first congregation of Quakers in Michigan in 1831. They also created a network of Underground Railroad stations in the Raisin River Valley. Daniel Smith was the first leader of the Raisin Valley Friends Meeting House. His daughter, Laura Smith Haviland became one of the most prominent equal rights activists and Underground Railroad operators in the nation.
