Chandragupta Maurya was the founder of the Mauryan Empire in India. He was the first ruler, who under the guidance of Chanakya, united almost the whole of India and for the first time ruled the unified India. At a very young age, Chandragupta developed a strong army, and defeated King Dhana Nanda of the great Nanda Empire. He also conquered the Indus Valley, which was ruled by the various ministers of Alexander- the great, along with many others. As a result, Chandragupta Maurya established the Mauryan Empire as the ever most powerful kingdom of India. Chandragupta Maurya eventually adopted Jainism and renounced the Mauryan kingdom to his son Bindusara at the age of 42. The building of Mauryan Empire by Chandragupta has played a crucial role in shaping the national identity of modern India. Chandragupta Maurya will continue to be recognized as an ideal ruler and a national hero.
