Congress created the state of Illinois on December 3, 1818, from the Illinois Territory. Its original capital was Kaskaskia but was quickly moved to Vandalia. In 1837, the capital relocated again, this time to Springfield. Abraham Lincoln made Illinois his home for most of his lifetime, moving there from Indiana in 1830 and leaving for Washington, DC, in 1861, to assume the presidency.
