(1417–1427).
Biography
Chimalpopoca was born to the Emperor
Huitzilihuitl and Queen
Ayauhcihuatl.
Rule
Chimalpopoca was crowned in 1417 (some sources say 1416 or 1418), at approximately 20 years old. At that time, Tenochtitlan was a tributary of the
Tepanec city of
Azcapotzalco
Azcapotzalco ( ; ; from ''wikt:azcapotzalli, āzcapōtzalli'' “anthill” + ''wikt:-co, -co'' “place”; literally, “In the place of the anthills”) is a Boroughs of Mexico City, borough (''demarcación territorial'') in Mexico City. Azcap ...
, which was ruled by his grandfather
Tezozomoc. This alliance, and the Mexicas' position within it, was strengthened by Tenochtitlan's loyalty during Tezozomoc's 1418 war with
Ixtlilxochitl I of
Texcoco. The conquered city was granted to Tenochtitlan as a tributary.
Nezahualcoyotl, displaced prince of Texcoco, was living in the mountains. Chimalpopoca interceded with Tezozomoc on his behalf, and Tezozomoc agreed to allow Netzahualcoyotl to live in Tenochtitlan under his protection.
In 1426 Tezozómoc assisted Chimalpopoca in the construction of a new aqueduct. This aqueduct was of wood, and ran from the elevated place of
Chapultepec to Tenochtitlan.
Chimalpopoca also had a causeway constructed to
Tlacopan. The causeway contained openings spanned by wooden bridges, which were removed at night.
Also during his reign he dedicated a stone for sacrifices in the Tlacocomoco section of Tenochtitlan. The conquest of
Tequizquiac is also attributed to him.
Family

Chimalpopoca was the son of
Huitzilihuitl, the previous ruler, but there are some sources that say he was a son of
Acamapichtli
Acamapichtli ( , meaning "Handful of reeds") was the first '' Tlatoani'', or king, of the Aztecs (or Mexica) of Tenochtitlan, and founder of the Aztec imperial dynasty. Chronicles differ as to the dates of his reign: according to the Codex Chim ...
, the first ruler of Tenochtitlan, making him
Huitzilihuitl's brother.
Gerónimo de Mendieta, in his ''
Historia eclesiástica indiana'', notes the discrepancy and concludes that Huitzilihuitl, Chimalpopoca and
Itzcoatl (Chimalpopoca's successor) must have been brothers, based on his understanding of the Aztec system of
succession
Succession is the act or process of following in order or sequence.
Governance and politics
*Order of succession, in politics, the ascension to power by one ruler, official, or monarch after the death, resignation, or removal from office of ...
.
[Gillespie (1989: pp. 12–14)]
He had many wives and children. One of the wives was his cousin
Matlalatzin. His son was
Tezozomoc, king of
Ecatepec.
Three versions of the family tree of the first Aztec rulers:
Chimalpopoca was a grandson of Acamapichtli and
Tezozomoc and half-brother of
Moctezuma I
Moctezuma I (–1469), also known as Montezuma I, Moteuczomatzin Ilhuicamina ( ) or Huehuemoteuczoma ( ), was the second Tlatoani, Aztec emperor and fifth king of Tenochtitlan. During his reign, the Aztec Empire was consolidated, major expansion ...
.
Death
When Tezozomoc died in 1426 after a long reign, he was succeeded by his son Tayauh (also known as
Tayatzin). However
Maxtla, ruler of
Coyoacan and brother of Tayauh, usurped the throne. Chimalpopoca allied with Tayauh, and so Maxtla had Chimalpopoca killed, though the details remain unclear. Maxtla also raised the tribute required from Tenochtitlan as further punishment for Chimalpopoca's actions.
Maxtla subsequently named their brother,
Itzcoatl, the ''tlatoani'' of the region. However, Itzcoatl quickly allied himself with
Nezahualcoyotl of Texcoco and
Totoquihuatzin of Tlacopan, and they collectively took down Maxtla, who had remained the Tepanec king.
