Complete Step by Step answer:
Chatrapathi Shivaji also known as Shivaji Bonsale was the founder of the Maratha Empire. Shivaji Bhonsale was an Indian empire and the greatest known Warrior king. He was an official member of the Bhonsle Maratha clan. Shivaji carved out an enclave from the declining Adil Shahi Sultanate of Bijapur. This was what had formed the beginning of the Maratha Empire. In the year 1674, he was officially crowned as the Chatrapati of his realm in the city of Raigad.

Throughout the course of life, Shivaji had engaged in alliances and hostilities with the Mughal Empire, the Sultanate of Golkonda and the Sultanate of Bijapur. He also engaged with the colonial powers of the Europeans. Chhatrapati Shivaji's military forces were the reason for the expansion of the Maratha sphere of influence, for capturing and building various forts and forming a huge Maratha navy in India. He had established the most competent and progressive civil rule along with well-structured administrative organisations in his empire. He revived various ancient Hindu political traditions and also court conventions and had promoted the usage of Marathi language and Sanskrit in his kingdom rather than the use of the Persian Language.

Note: Chatrapati Shivaji being one of the greatest and mightiest empires of his time, was immensely popular. His birthplace, the city of Mumbai, even today celebrates his reign. There are statues and even the Mumbai airport is named after the emperor Chatrapathi Shivaji.
