History

Dawson County was created in 1871 and named after Jacob Dawson, an early Nebraska settler and the first postmaster of Lincoln. Settlement expanded rapidly with the arrival of the Union Pacific Railroad, which established key stops across the county. Lexington, originally known as Plum Creek, became the county seat and an important transportation and agricultural hub.

The county’s early history includes the 1867 Plum Creek Massacre, a notable event during tensions between Native American tribes and westward expansion. Over time, Dawson County grew into one of Nebraska’s most productive agricultural regions, supported by irrigation from the Platte River and later by large‑scale meatpacking and manufacturing industries.
