god of war

A war god in mythology associated with war, combat, or bloodshed. They occur commonly in polytheistic religions.

Unlike most gods and goddesses in polytheistic religions, monotheistic deities have traditionally been portrayed in their mythologies as commanding war in order to spread religion. (The intimate connection between "holy war" and the "one true god" belief of monotheism has been noted by many scholars, including Jonathan Kirsch in his book God Against The Gods: The History of the War Between Monotheism and Polytheism and Joseph Campbell in The Masks of God, Vol. 3: Occidental Mythology.)
