According to various witnesses, Don Gonzalo–Mazatzin at the time–sent an emissary to find Cortés and offer his vassalage to the king of Spain, along with a gift of gold to prove his good intentions.
After Cortés' departure, Don Gonzalo sent ambassadors to neighboring provinces announcing his new alliance, which made him "very admired and respected".
His title and lands were respected by Spain, and his lineage continued controlling their expanded area for centuries as vassals of the Hispanic Crown.
This was a formal request of new privileges, such as total and permanent tax exemption for his entire city, as a reward for his grandfather's help during the conquest.
Probanzas de mérito are unreliable as information sources, since their main goal is to persuade the judge to grant a petition.
None of the Spanish conquerors who allegedly met Don Gonzalo refer to him by name or talk about their encounter.
Most letters and accounts sent by the conquerors to the king were either aimed at requesting resources or at highlighting their own deeds in order to obtain future favors.
