History

Cass County was established in 1855 and named after Lewis Cass, a prominent American statesman. Its early development centered on the Missouri River, where Plattsmouth became a major ferry crossing and trade hub for settlers moving west. The arrival of railroads in the late 19th century accelerated growth, connecting towns like Weeping Water, Louisville, and Elmwood to regional markets. Agriculture, limestone quarries, and river commerce shaped the county’s early economy, while proximity to Omaha and Lincoln later encouraged suburban expansion and tourism.

The county’s history reflects frontier migration, river‑valley settlement, and the evolution of small towns that remain central to local identity.
