It's metro population numbers over a million - a third of the entire state's population. During the 1800s, the US government was forcibly relocating Indian tribes from all over the country into the area known as Oklahoma Territory. There was one parcel of land that was never given over to any Indian tribe - the Unassigned Lands. In the 1880s, many frontier Americans wanted to move into this land.

Some people snuck over at night to stake out prime land early, hiding from the army patrols.
At noon, the cannon roared, and the hordes of people streamed over the line on wagons and buckboards, horseback, on foot and even on bicycles. Soon, nearly 10,000 people had staked out claims near the Oklahoma Station - what today is Oklahoma City. Claim jumping was common, as were boundary quarrels that led to fights and considerable bloodshed. Tents were thrown up in haphazard fashion, and mass confusion reigned supreme. Congress had made no provision for city government, so leaders had to be chosen to restore order.
