Akkalkot was the home to Shri Swami Samarth Maharaj, a 19th century saint who is believed by his devotees to be an incarnation of God Dattatreya.

Swami Samartha of Akkalkot is considered by many to be the very form of Sri Nrusimha Saraswati of Ganagapur. Occasionally, Swamy said that he was Nrusimha Bhan and that he was from kardalivan near Srisailam confirmed that he was Nrusimha Saraswati. Swamy took up numerous names at different places which made it hard to trace his travels.
