Do Illinois have three capitals?
Illinois was admitted to the Union
on December 3, 1818 becoming the 21st state to join the union.
Kaskaskie was the capital city in the Illinois Territory and
continued as the capital city in the state of Illinois until 1819
when the capital was moved to Vandalia. In 1837, the state
legislature moved the state capital to Springfield. Springfield is
the capital city in Illinois and has been since 1837.
