The importance of this alliance is quite controversial among historians. Numismatist John Allan theorized that Chandragupta defeated the Lichchhavi Kingdom at Vaishali and that the marriage of KumaraDevi to him was part of a peace treaty.  He suggested that the Gupta dynasty regarded marriage as honorable simply because of the ancestors of the ancient Licchavi royal family. The marriage likely helped Chandragupta expand his political power and dominance, which allowed him to assume the title of Maharajadhiraja.
