The Louisiana Purchase in 1803 hurt the Kaw. They were forced to move west by Native Americans from the east. They were also forced to move by White settlers who liked the "beautiful aspects" and "rich and exuberant soils" of the Kaw's land. In 1825, the Kaw ceded a big area of land in Missouri and Kansas to the United States. They did this in exchange for a promise of a $3,500 payment every year for twenty years. The promised payment was often late. Sometimes, the payments were taken by government officials and merchants.
