The Osage Indians occupied the land between the Osage River and Missouri River, in what is now Missouri. They eventually moved to lands in Oklahoma, Arkansas and Kansas.
Originally, the Osage Indians were a sedentary tribe that lived in mostly permanent lodgings made of earth and logs. The Osage hunted buffalo, but unlike tribes that followed game, they remained sedentary to grow crops. Negotiations with settlers for their land caused them to move their tribe westward.
The first negotiation, in 1810, persuaded the Osage to move to a reservation in Kansas. In 1872, a second negotiation caused the Osage to move to a reservation in Oklahoma. Today, the Osage are the wealthiest Indian tribe in the United States, with most of their population centered in Osage County, Oklahoma.
