Jean Nicolet is believed to be the first European to visit what is now Wisconsin. He canoed from Georgian Bay through the Great Lakes in 1634 and is believed to have come assure near Green Bay. Wisconsin became a territory of the United States in 1783, following the Revolutionary War. It was not until following the War of 1812 that an American presence was established. The economy shifted from fur trading to the mining of lead, which drew immigrants from the United States and Europe. During the early years of statehood, Wisconsin’s economy again shifted, this time to agriculture. In the 1890s, farmers shifted from wheat to dairy, with many immigrants continuing their cheese-making traditions.
