Early Roman religion blended indigenous beliefs with Etruscan and Greek influences. It centered on animistic spirits, abstract deities, and the concept of pax deorum. As Rome expanded, its pantheon grew, incorporating gods from conquered territories and evolving into a complex system of beliefs and practices. The Etruscans significantly shaped Roman religion, introducing divination, funerary customs, and architectural styles. Their influence extended to religious practices, deities, and rituals, including the Roman triumph. This fusion of beliefs laid the foundation for the rich tapestry of Roman religious life.
