Chandragupta I was a king of the Gupta dynasty, who ruled in northern India. His title Maharajadhiraja suggests that he was the first emperor of the dynasty. It is not certain how he turned his small ancestral kingdom into an empire, although a widely accepted theory among modern historians is that his marriage to the Lichchhavi princess Kumaradevi helped him extend his political power. Their son Samudragupta further expanded the Gupta empire.
