Kumaragupta (Mahendraditya) was ruler of the Gupta Empire from 415-455 CE. Like his father and predecessor, Chandragupta II, Kumaragupta was an able ruler. He retained, intact, the vast empire, which extended from North Bengal to Kathiawar and from the Himalayas to the Narmada. He ruled efficiently for nearly forty years. However, the last days of his reign were not good. The Gupta empire was threatened by the invasions of Pushyamitras. Wikipedia
