Wisconsin is a state in north USA. Wisconsin was the last State to be formed from the 'Old Northwest'. It was early explored by Nicolet, La Salle and French traders, who made the first settlement at Green Bay in 1639. In 1763 the treaty of Paris gave the territory to the English, under whose jurisdiction it remained until 1796, when it was ceded to the United States. In 1836 it was formed into a separate territory, and included besides its present area the present territory of Iowa and Minnesota and parts of the Dakotas. On May the 29th, 1848, the State was finally admitted into the Union. In 1872 the Graham liquor law was passed requiring a license for the sale of liquor and a bond for payment of any damages from its sale. In 1874 the Potter law fixed the railway rates for passengers and freight.
