Which Mexican state was never part of the Mayan civilization?

The Mexican state that was never part of the Mayan civilization is Sonora. Historically, the Maya civilization occupied areas in present-day southeastern Mexico, including states such as Yucatán, Quintana Roo, and parts of Oaxaca, which featured significant Mayan cities and cultural influence.

Sonora, located in the northwest region of Mexico bordering the United States, was not associated with the Maya civilization. Instead, it has its own distinct cultural and historical background influenced more by native groups such as the Pima and Yaqui, and later interactions with Spanish colonizers. This geographic separation and cultural context clarify why Sonora is correctly identified as the state that was never part of the Mayan political and cultural domains.
