History
Indigenous history
Native Americans lived in the Los Angeles Basin for thousands of years. The earliest known inhabitants of present-day Pasadena and its surroundings were members of the Hahamog-na tribe, a branch of the Tongva Nation. They spoke the Tongva language, belonging to the Northern subfamily of the Uto-Aztecan language group.
Pasadena means "valley" in the language of the Ojibwe, a Native American tribe not local to the region.

Why this record matters
The phrase “city in Los Angeles County, California, 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 13, 2026. The linked authority identifier is Q485176. VIAF identifies the subject as 157889787. The Library of Congress control number is n79027009. Authority coordinates are 34.148, -118.144. 5 of 5 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank. The first chronological checks are 2020 and 1886.
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.
