Chattrapati Shivaji Maharaj, Maratha King kills Afzal Khan, Adilshahi in the battle popularly known as Battle of Pratapgarh. This is also recognised as the first defence of Swarajya.

The Battle of Pratapgad was a battle fought on 10 November 1659, at the fort of Pratapgad, near the town of Satara, Maharashtra, India, between the forces of the Marathas under Shivaji and the Adilshahi troops under the Adilshahi general Afzal Khan. The Marathas defeated the Adilshahi forces. It was their first significant military victory against a major regional power.

Shivaji Bhonsale I (Marathi pronunciation: [ʃiʋaˑd͡ʒiˑ bʱoˑs(ə)leˑ]; c.19 February 1630 – 3 April 1680), also referred to as Chhatrapati Shivaji Maharaj, was an Indian ruler and a member of the Bhonsle Maratha clan. Shivaji carved out an enclave from the declining Adilshahi sultanate of Bijapur that formed the genesis of the Maratha Empire. In 1674, he was formally crowned the Chhatrapati of his realm at Raigad Fort.Over the course of his life, Shivaji engaged in both alliances and hostilities with the Mughal Empire, the Sultanate of Golkonda, Sultanate of Bijapur and the European colonial powers. Shivaji's military forces expanded the Maratha sphere of influence, capturing and building forts, and forming a Maratha navy. Shivaji established a competent and progressive civil rule with well-structured administrative organisations. He revived ancient Hindu political traditions, court conventions and promoted the usage of the Marathi and Sanskrit languages, replacing Persian in court and administration.Shivaji's legacy was to vary by observer and time, but nearly two centuries after his death, he began to take on increased importance with the emergence of the Indian independence movement, as many Indian nationalists elevated him as a proto-nationalist and hero of the Hindus.
