Thirumangai Alvar or Tirumangai Alvar or Tirumankai Alvar or Thirumangai Mannan (8th century AD) is the last of the 12 Alvar saints of south India, who are known for their affiliation to Vaishnava tradition. He is considered one of the most learned Alvars and the most superior Alvar in the context of composition of verses. He holds the title Narkavi Perumal, the mark of an excellent poet, and Parakala (Beyond Time). Though, he is respected as a Vaishnava saint-poet, he, initially, worked as a military commander, a chieftain and then a robber. After his conversion to Vaishnavism, he confronted practitioners of rival Hindu sect of Shaivism as well as Buddhism and Jainism.
