Four sampradayas and other traditions

The Vaishnavism traditions may be grouped within four sampradayas, each exemplified by a specific Vedic personality. They have been associated with a specific founder, providing the following scheme: Sri Sampradaya (Ramanuja), Brahma Sampradaya (Madhvacharya), Rudra Sampradaya (Vishnuswami, Vallabhacharya), Kumaras Sampradaya (Nimbarka). These four sampradayas emerged in early centuries of the 2nd millennium CE, by the 14th century, influencing and sanctioning the Bhakti movement.

The philosophical systems of Vaishnava sampradayas range from qualified monistic Vishishtadvaita of Ramanuja, to theistic Dvaita of Madhvacharya, to pure nondualistic Shuddhadvaita of Vallabhacharya. They all revere an avatar of Vishnu, but have varying theories on the relationship between the soul (jiva) and Brahman, on the nature of changing and unchanging reality, methods of worship, as well as on spiritual liberation for the householder stage of life versus sannyasa (renunciation) stage.

Beyond the four major sampradayas, the situation is more complicated, with the Vaikhanasas being much older than those four sampradayas, and a number of additional traditions and sects which originated later, or aligned themselves with one of those four sampradayas. Krishna sampradayas continued to be founded late into late medieval and during the Mughal Empire era, such as the Radha Vallabh Sampradaya, Haridasa, Gaudiya and others.
