In 1794, U.S.-born inventor Eli Whitney (1765-1825) patented the cotton gin, a machine that revolutionized the production of cotton by greatly speeding up the process of removing seeds from cotton fiber. By the mid-19th century, cotton had become America's leading export. The most significant effect of the cotton gin, however, was the growth of slavery. While it was true that the cotton gin reduced the labor of removing seeds, it did not reduce the need for enslaved labor to grow and pick the cotton.

The Louisiana Purchase was a very important purchase for many reasons. The Louisiana purchase stretched all the way from the rocky mountains, to the Appalachian mountains.  Thomas Jefferson bought the Louisiana territory from the France leader Napoleon. Thomas Jefferson wanted the New Orleans land but instead got a great deal for the whole land for just 15 million dollars! That's just 3¢ an acre! That doubled the United states size at that time. Although it was a very good deal for a huge amount of land, it started to cause some tensions between the south side and the north side. The north side wanted freedom for slavery, and wanted to stop the spread of slavery in the south. But the south wanted the opposite, and they wanted slaves for there lands and farms so they can earn extra money. This conflict then leaded into two different sides of the U.S.

The Lewis and Clark expedition lasted from May 1804 until September 1806. During the expedition, the corps of discovery (The name of the group) traveled nearly 8,000 miles (13,000 km)! During the expedition, they documented nearly 100 new species of animals, 178 new species of plants, and 140 maps of the region. This event may have led to the civil war because it helped America explore the new area more and see the new states that might have slaves for agriculture, and abolition movement areas. All that was known of the west before the expedition, was from the French traders or what was told in fantastical stories of the time-erupting volcanoes, mountains of salt, wooly mammoths, and seven foot tall beavers. After negotiating the Louisiana Purchase, Thomas Jefferson needed someone to explore the west, so he chose Lewis and Clark. Lewis and Clark led the U.S. Corps of Discovery on a historic expedition across the western lands of North America in early 1800s by Thomas Jefferson to map the territory, establish friendly trade relationships with Native tribes, and search for a water way to connect to the pacific ocean. Their discoveries directed the future course of American exploration and expansion.
