Overview: The Louisiana Purchase was the most important thing Thomas Jefferson did during his term as president.  He bought the Louisiana Territory in 1803 from France for about $15 million.  In those days, that was considered a good deal.  He bought so that the United States of America could expand from the east to the west coast.  That plan was called Manifest Destiny.
    The United States bought the Louisiana Territory because it contained the Mississippi River and that was a good source to trade upon.  The Louisiana Territory is 827,987 miles square.  It stretches from the Mississippi River to the Rocky Mountains.  It also ranges from the Canadian border to the Mexican border.  The Louisiana Territory was the biggest land mass ever bought by the United States.  It would double the size of the United States.
    The Louisiana Territory was also unexplored.  To fix this problem, the government sent explorers.  The most famous pair of explorers were Lewis and Clark who brought back priceless information.  They also sent the not-so-famous Zebulon Pike who brought back tales of southern territory.

William Clark

William Clark was probably best known for being part of the Lewis and Clark Expedition.  The Lewis and Clark Expedition was from 1804-1806.  The expedition was the first overland exploration of the American west and the Pacific northwest. 

In June 1803, Lewis asked Clark to join him as a co-leader on a government sponsored expedition through the Louisiana Territory to the Pacific Ocean.  Clark was promised a captain's commission to match Lewis' rank.  But bureaucratic confusion made him lieutenant

As commanding officers on the Lewis and Clark Expedition, Lewis and Clark informally decided leadership responsibilities.  The expedition through the Louisiana Territory to the Pacific Ocean made William Clark both influential and famous.
