The first settlers of Cassopolis were the Putnams, a small family from Indiana who took up residence in October of 1825. Their humble floorless home sheltered them from the harsh winter that followed and they survived the long months on boiled corn. But soon after, more pioneers moved into the area that, in 1829, became designated as Cassopolis village. As of the year 2000, 1,740 total people resided in the village.

Cassopolis was named after statesman prominent Lewis Cass, a native of New Hampshire and an illustrious U.S. Senator from Michigan before the American Civil War occurred. As the county seat of Cass County, the small community is cradled by Diamond and Stone Lake, offering waterfront real estate options and plenty of water sport activities. The nearby cities of Kalamazoo (Mich.) and South Bend (Ind.) present residents with great entertainment and cultural opportunities.
