As the fifth most populous of the 50 states, the state of Illinois has been home to U.S. Presidents: Abraham Lincoln, Ulysses S. Grant and Barack Obama. Ronald Reagan, who called California home during his political career, was born and raised in Illinois. The state is nicknamed "the Land of Lincoln.” While the most populous city in Illinois is Chicago, its capital is Springfield.
The organization of the central government of Illinois is largely the same as every other state (having three branches of government: executive, legislative, and judicial), but below this top level, the substructure of the state government is complex. Illinois has more units of local government than any other state - over 8,000. Illinois has two members of the U.S. Senate, a total of seventeen members of the U.S. House of Representatives, 118 members of the state House of Representatives and 59 members of the State Senate.
