Vaishnavism is one of the major Hindu denominations along with Shaivism, Shaktism, and Smartism. It is also called Vishnuism since it considers Vishnu as the sole supreme being leading all other Hindu deities, that is, Mahavishnu. Its followers are called Vaishnavites or Vaishnavas, and it includes sub-sects like Krishnaism and Ramaism, which consider Krishna and Rama as the supreme beings respectively.
According to a 2010 estimate by Johnson and Grim, Vaishnavism is the largest Hindu sect, constituting about 641 million or 67.6% of Hindus.
Vaishnava traditions centre on Hindu god Vishnu (centre) and his avatars.
