Chhatrapati Shivaji Maharaj is one of the most celebrated and respected figures in Indian history. He was born on February 19, 1630, in Shivneri Fort, near Pune, Maharashtra, and is known for founding the Maratha Empire in western India. His reign marked the beginning of the Maratha rise as a major political force in India, standing in opposition to the Mughal Empire and other regional powers.

Here are some key points from his history:

Rise to power

Shivaji Maharaj's military career started at a very young age, and he captured his first fort, Torna Fort, at the age of 16 in 1645. This was the beginning of his campaign to establish a Maratha kingdom.

His strategic skills, bravery, and tactics allowed him to rapidly expand his territory, gaining control of several forts along the Western Ghats and coastal areas. 

 

Conflicts with the Mughals

Shivaji's most famous conflict was with the Mughal Empire, led by Emperor Aurangzeb. Shivaji's defiance against the mighty Mughal forces is legendary.

He even conducted several daring raids into Mughal territory, including the famous raid on Surat in 1664.

In 1674, he crowned himself as the Chhatrapati (king) of the Maratha Empire in a grand ceremony at Raigad Fort.
