Gopala IV (Bengali : চতুর্থ গোপাল) previously called Gopala III, was the successor and son to the Pala king Kumarapala in the Bengal region of the Indian subcontinent, and nineteenth ruler of the Pala line reigning for at least 15 years, proved by a manuscript currently at British library.
[1] Gopala IV ascended the throne as a child, indicated by verse 30 of his Rajibpur copperplate, issued in 2nd year of his reign: Gopala IV "extends his own fame by raining dust of camphor playfully in his childhood."
Ryosuke Furui considers this to be the proof of Madanapala's regency for his young nephew.
Furui concluded that Madanapala usurped the throne soon after the second regnal year of Gopala IV.
However, Gopala IV had kept his presence until his 14th year in Bihar area, suggesting a parallel kingship.
