Cause and Consequence of the Louisiana Purchase: Lewis & Clark Expedition
Untitled Worksheet
Introduction to the Louisiana Purchase and Lewis & Clark
The Louisiana Purchase was a land deal between France and the United States in 1803, in which the US bought a vast territory west of the Mississippi River. This purchase doubled the size of the US and opened up new opportunities for exploration.
Lewis & Clark were appointed by President Thomas Jefferson to explore this new territory, with the goal of mapping the land, establishing American presence, and finding a route to the Pacific Ocean.
The expedition began in 1804 and lasted over two years, providing valuable information about the geography, native peoples, and resources of the west.
