Attica is a town in Harper County, Kansas, United States. As of the 2010 census, the city population was 626.
Land for the City of Attica was purchased in late June, 1884 and became the end of the Atchison, Topeka, and Santa Fe Railway. The town was incorporated later, on February 16th 1885, with a population of 1,500 people. The population grew further until the Cherokee Outlet in northern Oklahoma was opened by a Land run in 1893, at which point many people moved south to that territory.
Most of Attica is in Section 3 of Township 32 South of Range 9 West (S3-T32S-R9W) of the 6th Principal Meridian. The land for Attica was purchased from the Osage Land Trust, which also held the surrounding farmland. According to documents from Attica, the Osage Land Trust was held by the US government for the Osage tribe. Settlers could buy tracts of 160 acres (quarter-sections) for $1.25 / acre, and the money would go to the tribe. For reference, some of that land sold in 1909 for $12/acre.
