Chhatrapati Shivaji Bhosale :

Shivaji Bhosale (Marathi [3 April 1680), also known as Chhatrapati Shivaji Maharaj, was an Indian warrior king and a member of the Bhosale 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 as the Chhatrapati (Monarch) of his realm at Raigad.

Shivaji established a competent and progressive civil rule with the help of a disciplined military and well-structured administrative organizations. He innovated military tactics, pioneering the guerrilla warfare methods (Shiva sutra or ganimi kava), which leveraged strategic factors like geography, speed, and surprise and focused pinpoint attacks to defeat his larger and more powerful enemies. He revived ancient Hindu political traditions and court conventions and promoted the usage of Marathi and Sanskrit, rather than Persian, in court and administration.

Early life: Shivaji was born in the hill-fort of Shivneri, near the city of Junnar in Pune district on 6 April 1627 or 19 Feb. 1630. 
The Government of Maharashtra accepts 19 February 1630 as his birthdate; 
other suggested dates include 6 April 1627 or other dates near this day.Per legend, his mother named him Shivaji in honour of the goddess Shivai, to whom she had prayed for a healthy child.Shivaji was named after this local deity.Shivaji's father Shahaji Bhonsle was a Maratha genera who served the Deccan Sultanates.
 His mother was Jijabai, the daughter of Lakhujirao Jadhav of Sindkhed (Sindkhed Raja). At the time of Shivaji's birth, the power in Deccan was shared by three Islamic sultanates: Bijapur, Ahmednagar, and Golconda. Shahaji often changed his loyalty between the Nizamshahi of Ahmadnagar, the Adilshah of Bijapur and the Mughals, but always kept his jagir (fiefdom) at Pune and his small army with him.
Shivaji was a devout Hindu, but respected all religions within the region. Shivaji had great respect for other contemporary saints, especially Samarth Ramdas.
