Pax Deorum is a Latin term meaning "Peace of the Gods." In ancient Roman religion, it referred to the harmonious relationship between the gods and the state. Maintaining this peace was crucial for the prosperity of the Roman people, as it was believed that the favor of the gods ensured success in various aspects of life, including warfare and agriculture. To uphold the Pax Deorum, the Romans performed various rituals and sacrifices, often led by priests known as flamines. These ceremonies aimed to appease the gods, such as Jupiter and Mars, and to secure their blessings. The concept emphasized the importance of religious observance in Roman society.
