St. Vardan Mamikonian (born 387, Artaxata, kingdom of Armenia—died 451; feast day the last Thursday before Lent (in February or March)) was an Armenian military commander who is venerated as a saint and martyr in the Armenian Apostolic Church. The Persian attempt to impose Zoroastrianism on the Armenians provoked a rebellion, which ended when Vardan and his companions were slain at the Battle of Avarayr. Despite their victory the battle prompted the Persians to renounce their plans to convert Armenia by force, securing religious freedom for Armenian Christians. The Persians also deposed the traitorous Armenian governor.
