The Dacca copperplate inscription states that Srichandra, the Chandra king of Samatata-Harikela aided Rajyapala's son Gopala III to be crowned king by defeating Kamarupa armies in the Brahmaputra Valley & in the process, rescuing Rajyapala's wife, whom Ratna Pala had kidnapped & carried away to Kamarupa.
[2][3] The Baragaon plates, issued in the 25th regnal year of Ratnapala suggests that Brahma Pala abdicated in favour of his son.
The author of the inscription extravagantly praised Ratna Pala, describing him as a terror to the Saka king [since there was no Saka king at Ratnapala's time, the reference may be to the Hindu Shahis who were sometimes represented as the descendants of the Kushans]; to the Lord of Gurjaras (apparently the Gurjara-Pratiharas of Kanauj); to the Gauda monarch (Rajyapala, 908-40 AD, of Bengal and Bihar); to the ruler of Kerala; to the Vahikas (often spelt Bahikas; of Punjab, particularly in the Sialkot region); to the Tayikas (also spelt Tajika; they were Arabs, no doubt meaning the Arabs of Sind in the present case) as well as the Dakshinatya kings.
The Baragaon and Sualkuchi plate grants of Ratna Pala were issued in his 25th and 36th regnal years when the king was residing at Durjaya (capital).
He was the builder of many Siva temples, the donor of much wealth to the Brahmins, the performer of some sacrifices and the like (Indra Pala grant).
