History

Seneca was founded in 1857. It was named after Seneca County, Ohio. The first post office in Seneca was established in November 1858. Seneca grew up along the wagon route from St. Joseph, Missouri to Oregon and California. British explorer Richard Francis Burton en route to California in 1860 passed through town and noted: "... Seneca, a city consisting of a few shanties ..." Seneca was a station on the Pony Express of the early 1860s. The station was located in the Smith Hotel, at the present-day location of Fourth and Main Streets. Seneca was incorporated as a city in 1870.

Seneca was home to minor league baseball. The Seneca team played the 1910 season as members of the Class D level Eastern Kansas League, finishing in 2nd place. The team played home games at City Park.
