Chandragupta I married the Lichchhavi princess Kumaradevi, which may have helped him extend his political power and dominions, enabling him to adopt the imperial title "Maharajadhiraja". According to the dynasty's official records, he was succeeded by his son Samudragupta. However, the discovery of the coins issued by a Gupta ruler named Kacha have led to some debate on this topic: according to one theory, Kacha was another name for Samudragupta; another possibility is that Kacha was a rival claimant to the throne.
