Mars was the Roman god of war, and the month of March was named after him. The Latin name for March was Martius, meaning “the month of Mars,” making the connection direct rather than merely symbolic.
Mars was one of Rome’s most important gods. Unlike the Greek Ares, who was often portrayed as a destructive and disorderly figure, Mars held a more honored position in Roman religion. He protected the Roman state, its soldiers, and its agricultural community. Early Roman tradition connected him with both warfare and the fertility of fields.
March originally marked the beginning of the campaigning season, when winter conditions eased and armies could return to military activity. It was therefore a fitting month for Mars. Roman festivals associated with him, including the Equirria and the Feriae Marti, helped prepare the community and its horses for war.
Mars is also connected with the planet Mars, whose reddish appearance suggested blood and warfare to ancient observers. The same divine name survives in words such as martial and Martian, while Tuesday preserves the equivalent of Mars in several European languages.
