Tenango del Valle
municipality in the State of Mexico, Mexico

The municipality of Tenango del Valle is located in the southern portion of the Valley of Toluca in Mexico State, about 72 km southwest of Mexico City and 25 km south of Toluca. The municipal seat is the city of Tenango de Arista. While the seat is officially named Tenango de Arista, it is more commonly referred to as Tenango del Valle, as this was the original name of the town. Tenango del Valle is best known as the site of the Teotenango archeological site, which was a walled city inhabited from about 900 C.E. to 1550 C.E.
History of the town and municipality
The name "Tenango" shows the modern town's relationship with the nearby ruins of Teotenango. This site, when it was occupied, was called Tenango (or "place of the wall"). When the indigenous people were moved from this city to the valley floor below, the new village was also called Tenango. "Del Valle" (of the valley) was eventually added to distinguish the new village from the old city. Over time, the abandoned city of Tenango, became known as Teotenango ("walled city of the gods"). Both the archeological ruins and the Spanish village were referred to by the Aztec glyph for "Tenango" in the early colonial period in documents such as the Mendocino Codex. Today, this glyph is used to refer to the modern town and municipality.

Why this record matters
The subject matters to the general reference register because the source frames it as municipality in the State of Mexico, Mexico. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated May 2, 2026. The linked authority identifier is Q2607191. VIAF identifies the subject as 151539745. The Library of Congress control number is no00012627. Authority coordinates are 19.070, -99.630. None of the 3 selected statements returned an explicit reference. The first chronological checks are 1550.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. 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.
