The area was once home to the Pocumtuck tribe, who were driven away by settlers relocated in 1673 from Dedham. In retaliation, on September 18, 1675, the Indians attacked and killed Captain Thomas Lathrop and a small force in the Battle of Bloody Brook before being routed by reinforcements. Thereafter called Bloody Brook or Muddy Brook, South Deerfield in 1809 attempted to be set off from Deerfield in part because of the distance to its meetinghouse and in part because of religious differences with its minister, the Reverend Samuel Willard. The grant was refused, and the village remained part of Deerfield, but South Deerfield nevertheless dedicated its own meetinghouse in 1821. Situated beside the Connecticut River, it developed as a small farming community.
There are a variety of retail and service establishments in South Deerfield, including a hardware store, a family restaurant, the Polish American Citizens Club, and a small brewery. The town's Tilton Library and Frontier Regional High School are also in South Deerfield.

Religion
South Deerfield is home to a single unified Roman Catholic parish.[7] Until 2008, it was served by two parishes, St. Stanislaus Bishop & Martyr, intended to serve the Polish immigrant community, and St. James. In 2009, the Roman Catholic Diocese of Springfield announced that the two parishes would be merged,[8] with the new parish, Holy Family, to occupy the former facilities of St. Stanislaus.[7] The former church building and rectory of St. James were sold to a private purchaser, with a deed provision to ensure that the property not be put to any use inconsistent with the teachings of the Roman Catholic Church.[9] Additionally, in order to address a perceived lack of influence in church governance, in 1929 a breakaway group from St. Stanislaus founded Holy Name of Jesus church, affiliated with the Polish National Catholic Church.[10][11][12] A parish of the Ukrainian Greek Catholic Church, Descent of the Holy Spirit (formerly Descent of the Holy Ghost) was founded in 1920 as part of the Ukrainian Catholic Diocese of Stamford, and is active to the present day.[13][14]
