I want to know the answer to the following question:
Morelos, Oaxaca, Tlaxcala and Chiapas are important states which also have their own what?
All the background I'm provided with is that "The largest of these is in Huejotzingo, Puebla where most townspeople take part in mock combat with rifles shooting blanks, roughly based on the Battle of Puebla.". Is that enough to answer the question?
