History

Formed in 1855 from Cass County and Pierce County

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

Lancaster County was created by Nebraska Territory from Cass and Pierce counties, though it was not fully organized at that time. The county was fully organized on October 10, 1859. On February 15, 1864, Lancaster County gained part of Clay County, which was then eliminated; Seward and York were attached to Lancaster for judicial purposes. In October 1865, Seward was fully organized and detached from Lancaster, and York was transferred to Seward.

Boundary changes from the Newberry Library, Atlas of Historical County Boundaries.
