Teotihuacan is associated with the Teotihuacan culture, known for its advanced city planning, trade, and influence on Mesoamerican civilizations including the Maya and Aztecs.
Step-by-step explanation:
Teotihuacan is associated with the Teotihuacan culture, which flourished during the pre-Columbian era in Mesoamerica. This culture developed one of the largest cities in the ancient world, known for its monumental architecture, including the famous Pyramid of the Sun and Pyramid of the Moon. Teotihuacan exerted significant influence on neighboring cultures and regions, evidenced by its extensive trade networks and diplomatic and military interactions, particularly with the Maya civilization and later the Aztec people, who revered Teotihuacan as a sacred site. Despite its eventual decline around the middle of the seventh century CE, the city's cultural impact persisted throughout Mesoamerica.
