Was there ever a state level society in West Mexico before the Tarascans in the late postclassic? Considering that the area bordered large states for centuries I would imagine it would rub off and one would appear somewhere, but I could be wrong.
In Jalisco there was not any large Tarascan-like state. There were some smaller city-states, I guess you would categorize them. They were centered around places like Etzatlan, Ameca, Tonina (eastern side of Guadalajara), present-day Magdalena, and Tonina, for example. For the most part, Jalisco was quite divided and fractured among many ethnic and linguistic groups. It's what made the area somewhat easy to pacify since no one group was large enough to mount an effective resistance against the Spanish. However, the Spanish's failure to adequately identify all these groups allowed them to operate in the open and organize a rebellion around the Caxcan capital of Mixton in 1540. This rebellion occurred across Nueva Galicia (Jalisco) overnight as multiple communities threw out the Spanish and drove them from their villages. When the Spanish were able to reorganize they found that the Natives in the area retreated to hilltop fortresses that were difficult to attack. It took tens of thousands of Native allies from Central Mexico and Michoacan to overtake Mixton in 1541, which really angered and frustrated the Spanish officials. While the rebellion's back was largely broken with the capture of Mixton, the Spanish still had to attack other fortified hilltop settlements that continued to raid Spanish allied Natives and the Spanish themselves. Those that were not conquered retreated into the mountains. Some of them came down to support groups like the Zacatecos during the Chichimeca War, others continued to wage a guerilla war up until 1721 like the Cora did in present-day Nayarit. Ida Altman's book is really the best source for information on Contact period Jalisco if you are interested.
