Once consisting of several large land grants by Colonial Governor John Wentworth, the town was first named New Madbury, after the seacoast town of Madbury. In 1772, a road was built through Pinkham Notch, and the area was first settled in 1778 by Benjamin Copp and his family. In 1800, the community was renamed in honor of President John Adams, who was then in office. The name Adams stuck until the town was incorporated in 1829, when Andrew Jackson, the hero of the Battle of New Orleans, was inaugurated president. Governor Benjamin Pierce, a staunch backer of President Jackson, was influential in changing the name to Jackson. Only one vote was cast against the switch.
