Brief timeline of the history of the state of Missouri:
- 1673: French explorers Jacques Marquette and Louis Jolliet explored the Mississippi River and the Missouri River, marking the first recorded European contact with the region.
- 1762: France cedes the territory west of the Mississippi River, including present-day Missouri, to Spain as part of the Treaty of Fontainebleau.
- 1800: Spain returns the territory to France through the secret Treaty of San Ildefonso.
- 1803: The United States acquires the Louisiana Territory from France in the Louisiana Purchase, which includes present-day Missouri.
- 1804: The Lewis and Clark Expedition begins, with Meriwether Lewis and William Clark leading an exploration of the newly acquired territory, including parts of Missouri.
- 1812: Missouri Territory is established, with St. Louis designated as its capital. The territory's boundaries extend from the Mississippi River to the Rocky Mountains.
- 1821: Missouri becomes the 24th state of the United States. It is admitted as a slave state, which sparks controversy due to the growing debate over slavery in the country.
- 1838-1839: The forced removal of the Native American tribes, particularly the Cherokee Nation, from their ancestral lands in Missouri and other southeastern states to present-day Oklahoma occurs. This event is known as the Trail of Tears.
- 1849: The California Gold Rush prompts a wave of migration through Missouri, as settlers head west in search of gold and new opportunities.
- 1854: The Kansas-Nebraska Act is passed, which opens up the possibility of slavery in Kansas and Nebraska territories. This leads to violent conflicts between pro-slavery and anti-slavery factions, including the "Bleeding Kansas" incidents.
- 1861: Missouri becomes a battleground during the American Civil War. The state remains in the Union, but there are divided loyalties among its residents, resulting in internal conflicts and guerrilla warfare.
- 1875: St. Louis hosts the first World's Fair held in the United States, known as the St. Louis Exposition and Music Hall.
- 1896: The U.S. Supreme Court case Plessy v. Ferguson established the "separate but equal" doctrine, allowing racial segregation. This ruling has a significant impact on the state, including St. Louis.
- 1904: St. Louis hosts the Louisiana Purchase Exposition, also known as the St. Louis World's Fair, to commemorate the 100th anniversary of the Louisiana Purchase.
- 1945: The United Nations Charter is signed in San Francisco, with Missouri Senator Harry S. Truman playing a prominent role in the negotiations. Truman later becomes the 33rd President of the United States.
- 1965: The Gateway Arch, a symbol of St. Louis and the nation's westward expansion, is completed.
