In 1827, Fort Leavenworth became the first permanent settlement of white Americans in the future state. The Kansas–Nebraska Act became law on May 30, 1854, establishing Nebraska Territory and Kansas Territory, and opening the area to broader settlement by whites. Kansas Territory stretched all the way to the Continental Divide and included the sites of present-day Denver, Colorado Springs, and Pueblo.
