Kings/Tlatoani of Tlacopan

Probably the last of these quizzes I will be able to make. While I can find information on induvidual Tlaxcala rulers, I have had trouble finding an actual list of rulers with dates, and Tlaxcala was a regional power. I imagine finding information on the histories of other statelets outside of the Aztec Empire would be next to impossible. For most, there might be a record of the ruler at the time of spanish conquest or contact, but nothing beyond that. Leave Mesoamerica, and the vague resemblance of a local ruler to a "king" largely dissapears, It is hard to find lists of rulers when there isn't writing and your premodern state isn't a monarchy in the first place. That said, I might be able to pull something together for some of the Mixitec city states.
