The Lewis and Clark Expedition, launched as the Corps of Discovery in 1803 under President Thomas Jefferson, aimed to explore the vast Louisiana Territory and assert American sovereignty over the region.
Commanded by Captain Meriwether Lewis and Lieutenant William Clark, the team departed on May 14, 1804, from Camp Dubois in Illinois, journeying along the Missouri River through largely uncharted territory.
Facing extreme conditions, the explorers crossed the Rocky Mountains and followed the Columbia River to the Pacific Ocean, reaching their destination in November 1805 after about a year and a half of travel.
Key to the mission’s success were the contributions of guides and interpreters, notably Sacagawea and her infant son, Little Pomp, who helped establish relationships with Native American tribes along the route.
Upon their return in September 1806, the expedition’s extensive documentation of wildlife, geography, and plant species produced maps that guided future American migration west, reinforcing the nation’s expansionist vision.
Today, the anniversary of the Lewis and Clark Expedition honors the pioneering spirit and dedication that shaped American history and continues to inspire the pursuit of new frontiers.
