History
Formed in 1856 from Dodge County and Loup County
An old deed may name a county that no longer exists, or a boundary that has since moved.
Platte County was created on January 26, 1856, by Nebraska Territory from Dodge County and Loup County (extinct). The county was named after the Platte River. In 1860, Platte gained all of Monroe County (extinct), except the area that was part of the Pawnee Indian Reservation. Platte lost territory to the creation of Colfax County in 1869 and to Butler County in 2000.
