Early on, small trade centers, known as hamlets, emerged in Hassan Township to serve the needs of the settlers. The hamlet of Hassan was first settled in 1854 and then organized in 1860 along Territorial Road in Section 21. Between 1854 and 1881, Hassan contained a clustering of houses, a post office, St. John's Episcopal Church, a school and a town hall. Today, an altered school, a church and town hall remain. Today, a few businesses still thrive in Hassan, including Hassan Sand and Gravel, Minuteman Services, and Town and Country Landscaping, among others.
