The Otomi are among the oldest Indigenous civilizations in central Mexico, often regarded as the earliest inhabitants of the high plains. Their rich history spans thousands of years, with a deeply rooted social structure that has evolved over time. Their religious practices were shaped by a complex cosmology, where gods were associated with natural elements such as the sun, rain, and earth, with complex rituals and religious ceremonies held to honor these deities. Their connection to the natural world is reflected in a structured clan-based system, where different groups held spiritual significance tied to specific elements or celestial bodies. Their religious worldview was not only a matter of spirituality but also a guiding force in their daily lives, and their religious ceremonies were often central to community gatherings and political decision-making. They used visual symbols, including murals and codices, to represent their gods and cosmic beliefs, which also played a role in social cohesion. Despite centuries of external pressures, including Spanish colonization, many aspects of their religion are still practiced to this day.
