By the time Iowa attained statehood (December 28, 1848), its Territorial Legislature had created 44 counties. On January 15, 1851, the new State Legislature created another 49 counties, defining them by lines of survey. O'Brien was among the 49 units thus created. It consists of four survey townships, each formed by 36 square miles arranged in a 6x6 layout, for a nominal 576 square miles total area. The county was named for William Smith O'Brien, a leader for Irish independence in 1848. The new county's first settler arrived in 1856; Hannibal H. Waterman brought his wife and a daughter to the southeast portion (present Waterman Township). His homestead formed the nucleus of the county's first community, and a small building was erected there to function as a courthouse.
