Which expedition explored the newly acquired Louisiana Territory from 1804 to 1806?
Answer
Lewis and Clark Expedition
The Lewis and Clark Expedition explored the newly acquired Louisiana Territory from 1804 to 1806.
President Thomas Jefferson appointed Meriwether Lewis and William Clark to lead the expedition after the Louisiana Purchase. Their official goals included mapping the territory, studying its plants and animals, and finding a practical route to the Pacific Ocean.
The Corps of Discovery departed near St. Louis in May 1804 and traveled up the Missouri River before crossing the Rocky Mountains. The party reached the Pacific coast in November 1805 and returned to St. Louis in September 1806.
The expedition relied on extensive assistance from Native nations and interpreters, including Sacagawea, who traveled with the party and helped with communication and diplomacy. The journey did not create U.S. claims by itself, but it produced important geographic information for later American expansion.
