 Following the Spanish Conquest, Tlaxcala was divided into four fiefdoms (señoríos) by the Spanish corregidor Gómez de Santillán in 1545 (26 years after the Conquest).These fiefdoms were Ocotelolco, Quiahuiztlan, Tepeticpac, and Tizatlan.At this time, four great houses or lineages emerged and claimed hereditary rights to each fiefdom and created fictitious genealogies extending back into the pre-Columbian era to justify their claims.
