Madison's history started in 1829 when former federal judge, James Duane Doty purchased over 1,000 acres of swamp land on the isthmus between Lake Mendota and Lake Monona for building a city in the Four Lakes region. In 1836, the Wisconsin Territory was created and the territorial legislature convened in Belmont, Wisconsin. Wisconsin became a state in 1848. The City of Madison is still continuing to annex parts of the Town of Madison from back as 1848 and Fitchburg, Wisconsin, a suburb of Madison. The annexation will be completed on October 30, 2022.
