One difference between the toltecs and their teotihuacán predecessors was

The Toltecs regarded expansion and conquest as a sacred war, unlike their predecessors.

One of the major differences that set the Toltecs apart from the Teotihuacan predecessors was that the Toltecs set a precedent of cultural flows that predominated later Meso- American settlements. The Toltecs believed in the concept of divine authority and believed that every activity that they would engage in required divine consent. The elements of Toltec culture, political structures, and modes of exchange were incorporated with the Aztec civilization, and the Aztecs built on what was left of the Toltecs. Understandably, the Teotihuacán was the preceding civilization of the Toltecs, and its archaeological structure and remains were understood to have resembled either a center of religious importance or the political capital of a state or empire. The architectural structure of the city featured a feathered serpent, which was also the main deity worshipped by the inhabitants of the city.

Further Explanation-

The city of Teotihuacan was one of the earliest urban centers that emerged in Central American province of Mexico. Archaeologists refer to the architectural layout as one of the most advanced of those times. Historians have put forward several theories to understand the features of the city. The city dwellers displayed a remarkable architectural feat in utilizing the geographical relief to their own advantage, creating raised beds from swamped beds, and increasing agricultural productivity, which brought a wave of settlers. Moreover, volcanic eruptions enriched the fertility of the soil. An elaborate channel system helped in the transportation of essential items from one location to another. The religious iconography of the Toltecs features many religious practices that have been borrowed from the Teotihuacan culture such as building pyramids to honor the Solar and Lunar Gods, determination of festivals based on the position of the sun and moon, and the practice of sacrifice to the Gods.
