The Sinhgad Fort was initially known as "Kondhana" after the sage Kaundinya. The Kaundinyeshwar temple coupled with the caves and carvings indicate that the fort had probably been built around two thousand years ago. It was seized by Muhammad bin Tughlaq from the Koli in 1328 AD. Sinhagad: View from the "Pune Darwaja" Shahaji Bhosale, as the commander of Ibrahim Adil Shah I, was entrusted with the control of the Pune region. His son Shivaji, refused to accept the Adilshahi and initiated the task of setting up Swarajya. Shivaji gained control of Kondana in 1647 by convincing Siddi Amber, the Adilshahi Sardar who controlled the fort, that he, the son of Shahaji Bhosale, could manage the fort's defences optimally.
Bapuji Mudgal Deshpande played a key role in this activity. Adil Shah jailed Siddi Amber for this treasonous act and schemed to get it back. He imprisoned Shahaji Bhosale for a concocted crime and informed Shivaji. In 1649, Adil Shah traded the fort for Shahaji's release. Shivaji Maharaj recaptured it in 1656 again with the help of Bapuji Mudgal Deshpande who convinced the Fort commander by giving land in the newly created Shivapur village and peacefully gained control of the fort.
This fort saw attacks by Mughals in 1662, 1663 and 1665. In 1664, "Shahistekhan", a Mughal general, tried to bribe the people of the fort to hand it over to him, but was unsuccessful. Through the Treaty of Purandar, the fort passed into the hands of the Mughal army chief "Mirzaraje Jaysingh" in the year 1665. In 1670, Chhatrapati Shivaji Maharaj reconquered the fort for the third time and the fort came and stayed under the Maratha rule till 1689 A.D. After the death of Sambhaji, the Mughals regained control of the fort. The Marathas headed by "Sardar Balkawade", recaptured it in 1693.
Chatrapati Rajaram took asylum in this fort during a Mogul raid on Satara but died in the Sinhagad Fort on 3 March, 1700 A.D. In 1703, Aurangzeb conquered the fort. In 1706, it once again went into the hands of the Maratha's. Pantaji Shivdev of Sangola, Visaji Chafar and the Pant Pratinidhis played a key role in this battle. The fort remained under the Maratha rule till the year 1818, after which the British conquered it. The British however took 3 months to capture this fort, which was longest it took them to win any fort in Maharashtra.
