[VIDEO] Earlier this month the Tribune took a trip to the town of Kaskaskia, IL
As noted the town of Kaskaskia was the first state capital of Illinois located along the southwestern border of Illinois which is essentially the Mississippi River. According to the Wiki article about the town the population is only 14 as of 2010. It is the least populated area of this state.
Kaskaskia was the state capital until 1819. Illinois became a state in 1818 so it was only a year where state government was located. After 1819 thru 1839 our state capital was located in Vandalia, Illinois. As a matter of fact a State House was built in hopes that state government would remain in Vandalia.
Unfortunately for Vandalia, state government would move again to Springfield, Illinois where it has been since 1839. Also note that a future President of the United States, one Abraham Lincoln, was instrumental in moving the state capitol from Vandalia to Springfield.
