The 1803 <u>Louisiana</u> Purchase represents a major example of westward expansion in American history.
Explanation:
This purchase was made by President Thomas Jefferson from the French government for $15 million.
Napoleon Bonaparte decided to sell Louisiana territory to the Americans because he wanted to avoid a rapprochement between Americans and Great Britain. At that moment France was in the imminence of war against Great Britain and also had financial problems that led to the sale.
