The Sammakka–Saralamma Jathara, popularly known as the Medaram Maha Jathara, is recognized as Asia’s largest tribal religious congregation. Deeply rooted in ancient tribal customs and spiritual traditions, this sacred biennial festival is celebrated at Medaram Village, Tadvai Mandal, nestled within the dense forests of the Eturnagaram Reserve Forest, Mulugu District, Telangana.

Declared a State Festival in 1998, the Medaram Jathara has evolved from a humble tribal observance into one of the world’s most remarkable spiritual pilgrimages. During the Jathara, the otherwise quiet forest hamlet—home to fewer than 300 residents—transforms into a vast spiritual landscape, drawing over 1.5 to 1.75 crore devotees from Telangana, Andhra Pradesh, Odisha, Maharashtra, Madhya Pradesh, and other neighbouring states, all united in devotion to Sammakka and Saralamma Ammavaru.
