With his flawless warrior skills and unlimited courage, he ruled the Deccan region, parts of central India and parts of modern day Pakistan with a firm hand. It was due to his efforts that the Mughals faced a decline in their empire. Using guerrilla warfare techniques, he was successful in annexing a major portion of the Mughal Empire.
