The "Land Rush" refers to a period in the late 19th century when the United States government opened up vast tracts of land for settlement. This event allowed individuals to claim land, often in territories like Oklahoma, which had previously been designated for Native American tribes. The rush was characterized by a competitive race among settlers, who sought to establish homesteads and farms. The most famous Land Rush occurred on April 22, 1889, when thousands of people lined up to stake their claims. This event led to the rapid expansion of settlements and towns, significantly impacting the development of the American West and altering the lives of the indigenous populations living there.
