TLACOPAN (Kingdom)

TITLE: Tlatoani (personal name) Tepaneca tecuhtli
ANNEXATION: 13th August 1521
PREDECESSORS AND SHORT HISTORY: Tlacopan (also called Tacuba), was a kingdom founded at an unknown date by the Tepanecs or Tepaneca, a Mesoamerican people who had arrived in the Valley of Mexico in the late 12th or early 13th centuries and were welcomed by the semi-legendary Chichimeca ruler Xolotl. They then settled on the western shores of Lake Texcoco. It became subordinate to the rulers of nearby Azcapotzalco, the premier Tepanec city-state, one of whose rulers, installed his son, Aculnahuacatl Tzaqualcatl as the tlatoani in about 1400. It became a member of the Aztec Triple Alliance, comprising Tenochtitlan, Texcoco and Tlacopan, founded on 13th March 1428 and which formed the nucleus of the Aztec Empire. Tlacopan was, however, to remain a junior partner in the alliance, receiving only a fifth of the tribute gained from joint campaigns with its more powerful allies. Rulers were...
