What is the capital of Wisconsin?

The capital of Wisconsin is Madison. Established as the capital in 1837, Madison was chosen for its central location within the state and its accessibility to residents. The city is also home to the Wisconsin State Capitol building, which houses the offices of the governor and the legislature. Madison’s designation as the capital reflects its historical significance and the role it plays in the state's government and political affairs. The other options, while significant cities in Wisconsin, do not serve as the state capital. Milwaukee is known for its cultural and economic contributions, Green Bay is famous for its sports teams and historical roots, and Appleton has its own unique attributes, but none of these cities have the governmental designation of Madison.
