The city is surrounded on three sides by Tecumseh Township, but the two are politically independent. Raisin Township borders the southern edge of the city. The city was rated #93 in 2009, as one of 100 of the best small towns to live in by CNNMoney.The boundaries of Lenawee County were laid out by a proclamation of the Territorial Governor, Lewis Cass on September 10, 1822.
Lenawee remained attached to Monroe County, out of which it was formed, until an act of the Territorial Legislature passed on December 26, 1826, organized the county government. The first settlement in the county was made two years earlier, on May 21, 1824, in Tecumseh. The settlers, consisting of fifteen men, eleven women, and six children, all came from Jefferson County, New York. In 1823, Musgrove Evans had located the land and persuaded General Joseph W. Brown and the others to move to the site. Brown and Evans, along with Austin Eli Wing purchased land there and platted the village of Tecumseh in 1824. These founders appealed to Governor Cass to locate the county seat of Lenawee at Tecumseh.
