A gunshot at high noon on this day, April 22, 1889, began the famous Oklahoma land rush. Within nine hours, some 2 million acres became the private property of settlers who staked their claims. Riding as fast as they could, many found desirable plots already taken by "Sooners," individuals who entered the territory sooner than was permitted. The remaining land was assigned to the various Indian tribes, who joined together in approving the Constitution of the State of Oklahoma in 1907. The Preamble begins: "Invoking the guidance of Almighty God, in order to secure and perpetuate the blessings of liberty."
