President Thomas Jefferson makes the Louisiana Purchase. Haiti wins its independence from France. Lewis and Clark lead the Corps of Discovery.?

The Louisiana Purchase, completed in 1803 under President Thomas Jefferson, significantly expanded U.S. territory, doubling the nation's size and providing vast resources. Around the same time, Haiti achieved independence from France in 1804, becoming the first successful slave-led revolution in the Americas. Following these events, Lewis and Clark embarked on their expedition in 1804 to explore the newly acquired lands, mapping the territory and establishing American presence in the West. Together, these milestones shaped the early 19th-century landscape of North America and the quest for expansion.
