along with all the lands of Wisconsin Territory west of the Mississippi River. Democracy on the Wisconsin frontier Wyman calls Wisconsin a "palimpsest" of layer upon layer of peoples and forces, each imprinting permanent influences. He identified these layers as multiple "frontiers" over three centuries: Native American frontier, French frontier, English frontier, fur-trade frontier, mining frontier, and the logging frontier. Finally the coming of the railroad brought the end of the frontier. The historian of the frontier, Frederick Jackson Turner, grew up in Wisconsin during its last frontier stage, and in his travels around the state he could see the layers of social and political development. One of Turner's last students, Merle Curti used in-depth analysis of local history in Trempeleau County to test Turner's thesis about democracy. Turner's view was that American democracy, "involved widespread participation in the making of decisions affecting the common life, the development of initiative and self-reliance, and equality of economic and cultural opportunity. It thus also involved Americanization of immigrant." Curti found that from 1840 to 1860 in Wisconsin the poorest groups gained rapidly in land ownership, and often rose to political leadership at the local level. He found that even landless young farm workers were soon able to obtain their own farms. Free land on the frontier therefore created opportunity and democracy, for both European immigrants as well as old stock Yankees. Statehood By the mid-1840s, the population of Wisconsin Territory had exceeded 150,000, more than twice the number of people required for Wisconsin to become a state. In 1846, the territorial legislature voted to apply for statehood. That fall, 124 delegates debated the state constitution. The document produced by this convention was considered extremely progressive for its time. It banned commercial banking, granted married women the right to own property, and left the question of African-American suffrage to a popular vote. Most Wisconsinites considered the first constitution to be too radical, however, and voted it down in an April 1847 referendum. In December 1847, a second constitutional convention was called. This convention resulted in a new, more moderate state constitution that Wisconsinites approved in a March 1848 referendum, enabling Wisconsin to become the 30th state on May 29, 1848. Wisconsin was the last state entirely east of the Mississippi River (and by extension the last state formed entirely from territory assigned to the U.S. in the 1783 Treaty of Paris) to be
