USA HISTORY

Detailed explanation-1: -After the Louisiana Purchase Treaty was made, Jefferson initiated an exploration of the newly purchased land and the territory beyond the “great rock mountains” in the West. He chose Meriwether Lewis to lead an expedition, who in turn solicited the help of William Clark.

Detailed explanation-2: -When France offered to sell the Louisiana Territory to the United States in 1803, Jefferson wanted to seize the opportunity to double the size of the nation and to provide future generations with a seemingly inexhaustible supply of new farmland.

Detailed explanation-3: -Foreign Minister Talleyrand tells Livingston that France is willing to sell all of Louisiana. Monroe arrives in Paris and joins Livingston in negotiations with Finance Minister Barbé-Marbois. Monroe, Livingston, and Barbé-Marbois agree on terms of sale: $15 million for approximately 827, 000 square miles of territory.

Detailed explanation-4: -Known as the Corps of Discovery, the Lewis and Clark Expedition set out from Saint Louis in 1804 and returned in 1806. Jefferson directed Lewis and Clark to first and foremost find the elusive Northwest Passage, a body of water believed to connect the Mississippi River to the Pacific Ocean.
