Erstwhile Papannapet Samsthanam covered almost entire undivided Medak district. In the history it was said as part of Andhol Rajyam with 24 paraganas and was ruled by the princess Rai Bagan Maharani Shankaramma, daughter of Sanga Reddy and Rajamma. She was born in 1702 at Gaudicherla Village. The ruler of Papannapet Samsthanam Ramadurga Venkata Narasimha Reddy married her for her bravery. After the demise of Raja Narasimha Reddy in 1760, the power of Samsthanam went to in to the hands of Rani Lingayamma II with the prevailing political situations. When Peshwa of Maratha Empire invaded Nizam's territory, Rani Shankaramma countered them, for which she was honoured with Rai Bagan title and was restored to power as Rani of Samsthanam in 1764. She then built Sangareddi, named after her father Sanga Reddy Rajampet, named after her mother Rajamma. She was also credited with the building of Shankarampet after her name and Papannapet named after Merelli Papanna. She adopted Sadashiva Reddy who married Parvathi Devi, daughter of Gadwal Samsthanam ruler Somanatha Bhupala. Sadashivapet was named after her adopted son Raja Sadashiva Reddy. Rani Shankaramma died in 1774. Papannapet Samsthanam, which was already in legal disputes by the early 20th centuryafter the death of Raja Durga Reddy was merged into Hyderabad State in 1948, during the rule of Raja Ramachandra Reddy Bahadur. In the history Rani Shankaramma was compared with Rani Ahilya Bhai and Rani Rudrama Devi by historians for her administrative skills and valour. She was credited with agricultural development such as constructing ponds and was regarded as a social reformer for her acts of making Neerudi Papanna, a dalit as commander. Many folkloric stories were sung describing her valour. Historians such as B.N.Shastri said that Papannapet Samsthanam history is clearly recorded from the rule of Rani Shankaramma. Suravaram Prathapa Reddy mentioned Rani Shankaramma and Raja Sadashiva Reddy in "Golconda Patrika". Chidire Lakshmana Shastri who was the Raja purohit of Samsthanam published the history of Samsthanam titled "Medak Rajula Charitra" by gathering information from the books such as "Maa Poorva Vamshavali" by Rani Lingayamma, "Maa Vamsha Charitra" written in Urdu by Raja Venkata Narasimha Reddy, "Maa Samsthana Charitra", "Lingayamma Charitra" by Venkatadwari, Tirumalacharya's "Shaurya Rajya Vamshavali", "Shrimajjoginatha Charitra" by Mudigonda Ramakrishna Kavi.
