History

The area was inhabited by Native American groups before European‑American settlement in the 19th century. St. Joseph grew rapidly as a river port, a rail hub and as the eastern terminus of the Pony Express in 1860, a short‑lived but iconic mail route that linked the central United States to the West. The city's frontier era is often recalled in regional museums and preserved historic districts.

St. Joseph hosts colleges, hospitals and cultural institutions that serve the county and the surrounding region.
