What is a Sooner?
The unassigned lands of the Oklahoma Territory were opened up to settler claims on April 22, 1889. Thousands of people were in line on the border waiting for the signal to be given so they could race into the territory to claim a stake of land. Some people went in early to stake claims and they became known as "Sooners."
