Oklahoma City was settled on April 22, 1889, when the area known as the "Unassigned Lands" was opened for settlement in an event known as "The Land Run". Some 10,000 homesteaders settled the area that would become the capital of Oklahoma. The town grew quickly; the population doubled between 1890 and 1900. Early leaders of the development of the city included Anton Classen, John Shartel, Henry Overholser and James W. Maney.
