Visitor Information

About First Capitol

First Missouri State Capitol State Historic Site in St. Charles preserves the building where Missouri’s first state government met from 1821-1826 — in rented rooms above a hardware store and dry goods shop. Missouri became the 24th state through the Missouri Compromise of 1820, which paired Missouri (slave state) with Maine (free state) to maintain the Senate balance. This compromise delayed but could not prevent the Civil War.

Thomas Jefferson called it “a fire bell in the night.” Lewis & Clark: The Lewis & Clark Expedition departed from nearby Camp Dubois in 1804.

Frequently Asked Questions

What was the Missouri Compromise?

The Missouri Compromise (1820) was a landmark agreement that admitted Missouri as a slave state and Maine as a free state — while banning slavery in the Louisiana Purchase territory north of 36°30′. It maintained the balance between free and slave states for 30 years. Thomas Jefferson recognized its danger — calling it “a fire bell in the night” that foreshadowed the Civil War.
