History
Foundation
The area was occupied by Native Americans as early as 100 BC, as indicated by the Portsmouth Earthworks, a ceremonial center built by the Ohio Hopewell culture between 100 and 500 AD.
According to early 20th-century historian Charles Augustus Hanna, a Shawnee village was founded at the site of modern-day Portsmouth in late 1758, following the abandonment of Lower Shawneetown.
European-Americans began to settle in the 1790s after the American Revolutionary War, and the small town of Alexandria was founded. Located at the confluence, Alexandria was flooded numerous times by the Ohio River and the Scioto River.
In 1796, Emanuel Traxler became the first person of European descent to permanently occupy land in what would later be known as Portsmouth, after the United States gained its independence.
In 1803, Henry Massie found a better location slightly east and somewhat removed from the flood plains. He began to plot the new city by mapping the streets and distributing the land.

Why this record matters
The phrase “city in Scioto County, Ohio, United States” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The strongest evidence will usually combine a dated visual record with documents produced by the authority responsible for the place. The source revision retrieved here is dated Sep 23, 2026. The linked authority identifier is Q685335. VIAF identifies the subject as 267227845. The Library of Congress control number is n81053410. Authority coordinates are 38.743, -82.966. 4 of 5 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank. The first chronological checks are 2020, 1758, 1796 and 1803.
A single description cannot reconcile every naming convention, rebuilding phase or administrative transfer associated with a place. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
