Sempronius was part of the Central New York Military Tract. The first settler arrived c. 1793. Sempronius became a town in 1799 by breaking away from Scipio, but its area was later reduced by the formation of newer towns: Marcellus (Onondaga County) in 1804, Moravia and Niles in 1833.
Sempronius was the birthplace of the 12th Governor of Illinois (1860–1861) John Wood on December 20, 1798.
