After a decade of abolitionist and proslavery conflict that gave the territory the nickname Bleeding Kansas, Kansas was admitted to the Union in 1861 as the 34th state. Topeka was chosen as the capital, with Dr. Charles Robinson as the first governor. In 1862, Cyrus K. Holliday donated a tract of land to the state for the construction of a state capitol. Construction of the Kansas State Capitol began in 1866. About 37 years were needed to build the capitol, first the east wing, and then the west wing, and finally the central building, using Kansas limestone. In fall 1864, a stockade fort, later named Fort Simple, was built in the intersection of 6th and Kansas Avenues to protect Topeka, should Confederate forces then in Missouri decide to attack the city. It was abandoned by April 1865 and demolished in April 1867.
