History

Formed in 1888 from Albany County and Laramie County

An old deed may name a county that no longer exists, or a boundary that has since moved.

Converse County was created by Wyoming Territory from Albany and Laramie but was not fully organized until May 21, 1888, when it was detached from both counties for administrative and judicial purposes. In 1911, Converse lost territory to the creation of Niobrara County, while gaining territory along its boundary with Laramie; boundaries with Johnson, Natrona, and Weston were adjusted to run on federal land survey lines. In 1955, Converse gained territory from Albany County following a special election held on July 12, 1955.

Lost territory Converse lost to creation of Niobrara. Niobrara not fully organized, attached to Converse "for judicial, revenue and election purposes." Converse gained territory along former boundary with Laramie; boundaries with Johnson, Natrona, and Weston adjusted to run on federal land survey lines. Technically, Niobrara had been created on 14 February 1911, but the several boundary laws of February 1911 were not passed in the intended sequence and mapping them in strict chronological order is not practical. By treating the law of 21 February as the basic structure that the other laws modify, the mapping reflects the intent of the legislature.
