Telangana state is known for its unique culture and traditions. The cultural milieu of Telangana is marked by rich diversity, influenced by different folklores and legends. Sammakka Saralamma Jathara or Medaram Jathara is a tribal festival of honouring the goddesses in the state of Telangana, India.

The Jatara begins at Medaram in Tadvai Mandal, Jayashankar Bhupalpally district. Medaram is a remote hamlet of Dandakaranya forest range. It commemorates the fight of a mother and daughter, Sammakka and Saralamma, with the reigning rulers against an unjust law. It is believed that after Kumbha Mela, it is Medaram jathara which attracts the largest number of devotees in the country. There are many legends about the miraculous powers of Sammakka.

According to a tribal story, during 13th century, a tropp from the Koya tribal community was returning from a trip when they saw a little girl playing with the tigers. The head of the troop saw the girl and inspired by her bravery, he adopted her and named her as Sammakka. Later she married a headman of a neighboring tribal group and had a daughter, Sarakka. Both the mother and daughter protested the Kakatiya kings who forced the tribes to pay taxes. Both the women fought bravely and reportedly lost their lives. The Koya community constructed this temple as a token of gratitude. Annually an event called Sammakka Saralamma jathara is held which is considered as one of the largest tribal festivals in the world.

Sammakka Sarakka Jathara is the largest tribal religious congregation in the world, held every two years (biennially), with approximately ten million people converging on the place, over a period of four days. This fair is said to be the largest repeating congregation of tribal communities in the world. In the year 2018, approximately 1 crore people attended the world's largest tribal festival.
The actual festival begins during the month of Magha, on Suddha Pournami i.e. full moon day in the evening when Sarakka is traditionally brought from Kanneboyinapalle village in the forest, and then placed on an earthen platform which is raised under a tree. By the sunset of the next day, the main goddess Sammakka is then brought from Chilukalagutta. There are two platforms, one for goddess Sammakka and other is for goddess Sarakka. They are in the form of bamboo sticks, which is smeared with vermilion and turmeric. Since times immemorial, there is a huge tree, which stands on Sammakka gadde.
When the priests get the ochre box and other important relics from a hidden forest location, there is a great tumult accompanied by frenzied beating of drums, trumpet blowing and yells. The coconuts and jaggery offering becomes piled at the foot of old trees. Sammakka Sarakka Jathara is celebrated once in two years for four days during Magha purnima. Sammakka Sarakka Jathara will be held from February 5th to 8th, 2020.
