Helena, Montana
capital city of the U.S. state of Montana and seat of Lewis and Clark County
Helena (; ) is the capital of the U.S. state of Montana and the county seat of Lewis and Clark County. Its population was 32,091 at the 2020 census, making it the sixth-most populous city in Montana, but the fifth-least populous state capital in the U.S. It is the principal city of the Helena, Montana metropolitan area, which includes all of Lewis and Clark, and Jefferson counties; the MSA's population was 83,058 at the 2020 census.
Helena was founded as a gold camp during the Montana gold rush on July 14, 1864, following the discovery of gold at Last Chance Gulch by the Four Georgians. It was formally established on October 30, 1864. Due to the gold rush, Helena became a wealthy city, with approximately 50 millionaires inhabiting the area by 1888. The concentration of wealth contributed to the city's prominent, elaborate Victorian architecture. The local daily newspaper is the Independent Record. The city is served by Helena Regional Airport (HLN).
History
The Helena area was long inhabited by various indigenous peoples. Evidence from the MacHaffie and Indian Creek sites on opposite sides of the Elkhorn Mountains southeast of the Helena Valley show that people of the Folsom culture lived in the area more than 10,000 years ago.

Why this record matters
The phrase “capital city of the U.S. state of Montana and seat of Lewis and Clark County” 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.
Place names and jurisdictional language are key evidence: both can reveal earlier catalogue descriptions and overlooked record series. The source revision retrieved here is dated Sep 7, 2026. The linked authority identifier is Q38733. VIAF identifies the subject as 141754283. The Library of Congress control number is n80007662. Authority coordinates are 46.593, -112.035. 4 of 5 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank. The first chronological checks are 2020, 1864 and 1888.
Modern boundaries and familiar names can conceal earlier jurisdictions or structures that do not align with the present site. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
