Maurya Empire
Some later authors, such as Dhundhi-raja (an 18th-century commentator on the Mudrarakshasa and an annotator of the Vishnu Purana), state that the word "Maurya" is derived from Mura and the mother of the first Maurya king. However, the Puranas themselves make no mention of Mura and do not talk of any relation between the Nanda and the Maurya dynasties. Dhundiraja's derivation of the word seems to be his own invention: according to the Sanskrit rules, the derivative of the feminine name Mura (IAST: Murā) would be "Maureya"; the term "Maurya" can only be derived from the masculine "Mura".
