Vandalia was founded in 1819 as a new capital city for Illinois. The previous capital, Kaskaskia, was unsuitable because it was on the south-east border of the new state and under the constant threat of flooding. The more centrally located townsite, located in Bond County at the time, was hastily prepared for the 1820 meeting of the Illinois General Assembly. In 1821, Fayette County was created, including Vandalia.
