Hunter County, now extinct, was one of the counties created in 1855, by the first territorial legislature. It was bounded as follows: "Beginning at the southeast corner of Butler county; thence south to the southern boundary of the territory; thence west 30 miles; thence north to a point west of the place of beginning; thence east 30 miles to the place of beginning." In 1857, the county was enlarged by extending the western boundary to the line between ranges 4 and 5 east. In 1860 Irving county was created out of the northern part of Hunter, and in 1864 Butler county was enlarged to include both Irving and Hunter, which disappeared. The greater portion of what was once the county of Hunter is now included in Cowley county.
