Chandragupta I was born in 305 A.D. He married a Lichchhavi princess named Kumaradevi. Through this matrimonial alliance, he gained enormous power and used it to his great advantage. He launched a series of military expansions, pushing the kingdom's boundaries westward. By 320 A.D., he proclaimed himself Maharaj-adhiraja. Many historians consider 320 A.D. was the beginning of the Gupta dynasty.
