Answer:
the Louisiana purchase and New Orleans
Step-by-step explanation:
The Louisiana Purchase (1803) was a land deal between the United States and France, in which the U.S. acquired approximately 827,000 square miles of land west of the Mississippi River for $15 million.Napoleon agreed. On April 11, Foreign Minister Charles Maurice de Talleyrand told Livingston that France was willing to sell all of Louisiana. Livingston informed Monroe upon his arrival the next day.
Seizing on what Jefferson later called "a fugitive occurrence," Monroe and Livingston immediately entered into negotiations and on April 30 reached an agreement that exceeded their authority — the purchase of the Louisiana territory, including New Orleans, for $15 million. The acquisition of approximately 827,000 square miles would double the size of the United States.
