Seth Hastings (April 8, 1762 – November 19, 1831) was a United States representative from Massachusetts and a prominent Federalist lawyer and jurist in the early republic. He was born in Cambridge, in the Province of Massachusetts Bay, to Seth and Hannah (Soden) Hastings. Through his father’s line he was a descendant of Thomas Hastings, a colonist from the East Anglia region of England who emigrated to the Massachusetts Bay Colony in 1634, a lineage that placed the family among the long-established New England settlers.
Hastings received a classical education and attended Harvard University, from which he graduated in 1782. Following his graduation, he pursued legal studies and was admitted to the bar in 1786. He then settled in Mendon, Massachusetts, where he commenced the practice of law. As a young attorney in a growing rural community, he quickly became involved in local affairs, building a reputation that would support his later political career.
In addition to his legal practice, Hastings held several important local offices in Mendon. He served as town treasurer in 1794 and 1795, managing the municipality’s finances during the early years of the new federal government. In 1796 he was elected one of the first school commissioners, participating in the organization and oversight of local education at a time when Massachusetts communities were formalizing their public school systems. These roles reflected both his standing in the community and his interest in civic administration.
Hastings entered national politics as a member of the Federalist Party. He was elected to the Seventh Congress to fill the vacancy caused by the resignation of Levi Lincoln, and took his seat on August 24, 1801. He was subsequently reelected to the Eighth and Ninth Congresses, serving continuously in the U.S. House of Representatives from August 24, 1801, to March 3, 1807. During his tenure in Congress, he represented Massachusetts at a time of intense partisan conflict between Federalists and Jeffersonian Republicans, participating in legislative debates over the scope of federal power, commerce, and foreign policy in the years leading up to the Embargo and the War of 1812. He declined to be a candidate for renomination in 1806, thereby ending his congressional service at the close of the Ninth Congress.
After leaving Congress, Hastings remained active in Massachusetts state and local government. He served as a member of the Massachusetts State Senate in 1810 and again in 1814, contributing to state legislative deliberations during the politically charged period surrounding the War of 1812, when New England Federalists were particularly vocal on issues of trade and national defense. His legal expertise and prior legislative experience made him a significant figure in state politics even after his departure from the national stage.
Hastings’s judicial career culminated in his appointment as chief justice of the court of sessions for Worcester County, a position he held from 1819 to 1828. In that capacity, he presided over a court responsible for a range of county-level judicial and administrative matters, including oversight of local governance, infrastructure, and certain criminal and civil proceedings. His nearly decade-long tenure as chief justice underscored his standing as a respected legal authority in central Massachusetts and extended his influence well beyond his earlier legislative roles.
Hastings spent his later years in Mendon, where he had long resided and practiced law. He died there on November 19, 1831. He was interred in the Old Cemetery in Mendon, reflecting his deep and enduring ties to the community he had served in multiple capacities. His family continued his tradition of public service; his son, William Soden Hastings, also represented Massachusetts in the United States House of Representatives, further cementing the Hastings family’s place in the political history of the Commonwealth.
