History of Portsmouth, NH

trade between upstream industries and mercantile interests abroad, the port prospered. Fishing, lumber and shipbuilding were principal businesses of the region. Enslaved Africans were imported as laborers as early as 1645 and were integral to building the city's prosperity. Portsmouth was part of the Triangle Trade, which made significant profits from slavery.

At the town's incorporation in 1653, it was named Portsmouth in honor of the colony's founder, John Mason. He had been captain of the port of Portsmouth, England, in the county of Hampshire, for which New Hampshire is named. In 1679, Portsmouth became not only the colonial capital, but also a refuge for exiles from Puritan Massachusetts.

When Queen Anne's War ended in 1712, the town was selected by Governor Joseph Dudley to host negotiations for the 1713 Treaty of Portsmouth, which temporarily ended hostilities between the Abenaki Indians and English settlements of the Province of Massachusetts Bay and New Hampshire.

In 1774, in the lead-up to the Revolution, Paul Revere rode to Portsmouth warning that the British were coming, with warships to subdue the port. Although the harbor was protected by Fort William and Mary, the rebel government moved the capital inland to Exeter, safe from the Royal Navy. The Navy bombarded Falmouth (now Portland, Maine) on October 18, 1775. African Americans helped defend Portsmouth and New England during the war. In 1779, 19 slaves from Portsmouth wrote a petition to the state legislature and asked that it abolish slavery, in recognition of their war contributions and in keeping with the principles of the Revolution. Their petition was not answered then, but New Hampshire later ended slavery.
