Kartikeya (IAST: Kārttikeya), also known as Skanda, Subrahmanya, Shanmukha or Muruga, is the Hindu god of war. He is generally described as the son of the deities Shiva and Parvati and the brother of Ganesha.
Kartikeya has been an important deity in the Indian subcontinent since ancient times. Mentions of Skanda in the Sanskrit literature data back to fifth century BCE and the mythology relating to Kartikeya became widespread in North India around the second century BCE. Archaeological evidence from the first century CE and earlier shows an association of his iconography with Agni, the Hindu god of fire, indicating that Kartikeya was a significant deity in early Hinduism. Kaumaram is the Hindu denomination that primarily venerates Kartikeya. Apart from significant Kaumaram worship and temples in South India, he is worshipped as Mahasena and Kumara in North and East India. Muruga is a tutelary deity mentioned in Tamil Sangam literature, of the Kurinji region. As per scholars of religion, the Tamil deity of Muruga coalesced with the Vedic deity of Skanda Kartikeya over time. He is considered as the patron deity of Tamil language and literary works such as Tirumurukāṟṟuppaṭai by Nakkīraṉãr and Tiruppukal by Arunagirinathar are devoted to Muruga.
