Illinois. Territorial General Assembly. House of Representatives.

After Illinois became a territory of the second grade in 1812, its citizens could elect its own House of Representatives. This House then nominated ten of its members, from which the U. S. Congress chose five members to form the upper chamber of the new bicameral General Assembly. The General Assembly, comprised of the House and the new Legislative Council replaced the Council of Revision as the legislative branch of territorial government until Illinois obtained statehood in 1818.
