Today’s Nevada counties did not always exist in the present form. They went through many different changes in the space of a few short years. Nevada Counties were first formed while part of the Mississippi Territory, and after that the Nevada Territory.
Nevada Territorial Counties
On November 25, 1861, the first Nevada Territorial Legislature established nine counties.
The Nevada Territory, was organized on March 2, 1861. Nevada was admitted to the Union on October 31, 1864 as the 36th State with 11 counties.
Nevada Counties Today
Carson City, the state capital, is also an independent city, which doesn’t belong to any county. However, it has a similar status to that of the 16 counties in the state.
Carson City used to be the county seat of Ormsby County, but the two were consolidated in 1969.
Nevada is divided into political jurisdictions designated as counties. Carson City is officially a consolidated municipality; however, for many purposes under state law it is considered to be a county.
There are some Nevada counties that no longer exist because they were discontinued, renamed or merged with another county. These are important for genealogy research purposes.
