Unit 7 - Louisiana Purchase

Lewis and Clark were chosen to explore the Louisiana Territory. They were selected by President Thomas Jefferson to lead an expedition to explore the newly acquired territory and find a route to the Pacific Ocean. Lewis and Clark, along with their team of explorers, embarked on their journey in 1804 and successfully completed their mission, documenting and mapping the vast territory and establishing relationships with Native American tribes along the way.

Thomas Jefferson served as president when the U.S. acquired the Louisiana Purchase. This historic event occurred in 1803 during Jefferson's presidency. The Louisiana Purchase was a significant expansion of the United States, doubling its size and opening up vast new territories for settlement and exploration. Jefferson was a strong advocate for westward expansion and saw the acquisition of the Louisiana Territory as a great opportunity for the young nation.

France sold the Louisiana Territory to the United States. This sale, known as the Louisiana Purchase, occurred in 1803. It was a significant event in American history as it doubled the size of the United States and opened up vast new territories for settlement and exploration. France had originally acquired the Louisiana Territory from Spain through the Treaty of San Ildefonso in 1800, but due to financial difficulties and the threat of war with Britain, Napoleon Bonaparte decided to sell it to the United States.

Sacagawea served as a guide to the men who explored the Louisiana Territory. She was a Shoshone woman who accompanied the Lewis and Clark expedition in the early 19th century. Her knowledge of the land, language skills, and ability to navigate difficult terrain proved invaluable to the expedition. Sacagawea played a crucial role in establishing peaceful relationships with Native American tribes they encountered and helped the explorers survive and navigate through unfamiliar territory.

The U.S. originally tried to buy New Orleans when they were offered the Louisiana Territory.

The slogan "Millions for defense, sir, but not one cent for tribute!" came about because of the bribery attempt known as the XYZ Affair. The XYZ Affair was a diplomatic incident between the United States and France in the late 18th century. French officials demanded bribes from American diplomats in order to negotiate a peace treaty. This slogan was a rallying cry for Americans who were outraged by the attempt at bribery and were determined to defend their country without giving in to extortion.

The Supreme Court established the power of judicial review in the Marbury v. Madison decision. This power allows the Court to declare a law unconstitutional.
