Perumal (பெருமாள் ) or Tirumal (திருமால் ) is a Hindu deity. Perumal is worshipped mainly among Tamil Hindus in South India, Sri Lanka, and the Tamil diaspora, who consider Perumal to be a form of Vishnu.
Some of the earliest known mentions of Perumal, and the Tamil devotional poems ascribed to him, are found in Paripāṭal – the Sangam era poetic anthology. He is a popular Hindu deity particularly among Tamils in Tamil Nadu and the Tamil diaspora, and in Vaishnava temples. One of the richest and largest Hindu temples complexes dedicated to Perumal is the Venkateshvara temple in Tirupati, Andhra Pradesh. Other significant institutions include Srirangam's Ranganathaswamy temple, Kanchipuram's Varadaraja Perumal temple, and Thiruvananthapurum's Padmanabhaswamy Perumal temple.
Scholars believe that both Perumal and Tirumal ultimately trace their origin to a tribal confederacy known as the Mallas in ancient India, whose name was Dravidian for "people of the mountains". Both of these terms were originally titles conferred by the Mallas upon their great chiefs and kings. This title was eventually employed as an epithet for the deity Vishnu, until its original meaning was widely forgotten over the course of time. However, in some regions of Kerala, Perumal continued to be employed as its original usage as an honorific for a ruler.
Perumal is also considered to be formed by two words Perum and al. Perum means great and al means person (used for god here). Therefore Perumal means the "great god" who showers his divine grace on people. He is considered the supreme god of Vaishnavism.
The deity Perumal is identified with Mayon, literally meaning, "the dark-complexioned one", who is first referenced in the texts Purananuru and Pattupattu. Regarded to be the Tamil equivalent of Krishna, poetry from this period compares his dark skin to the ocean. Originally a folk deity, he was syncretised with Krishna and Vishnu, gaining popularity in the Sri Vaishnava tradition. His consort is Lakshmi, the goddess of fortune, beauty, and prosperity, appearing in even the earliest strata of Tamil poetry.
