Answer:
Louisiana Purchase
Explanation:
The Louisiana Purchase was a transaction completed in 1803. In it, the United States purchased a vast expanse of land from France for $15 million. This territory was to make the country twice as large, and it included the Mississippi River, Rocky Mountains, Gulf of Mexico, and Canada. So, it turned out that with this great victory, America had a chance to access valuable resources and trade further into the west, bringing new frontiers for trade and expansion.
