Summary
5 May 1866 - The US removed the northwest corner from Arizona Territory (parts of Pah-Ute and Mohave counties) and gave that land to the State of Nevada.[18] Nevada used that land to add to Lincoln and Nye counties. But Arizona held to its previous claim to that land and opposed this transfer, twice petitioning congress to repeal the law. Up thru 1868, representatives from Pah-Ute County attended the Arizona Legislature.
