Just as the British had done, both the Dutch and Yang Dipertuan Muda then desperately tried to win the royal regalia from Engku Puteri. The reluctant Abdul Rahman, believing he was not the rightful heir, decided to move from Lingga to Terengganu, claiming that he wanted to celebrate his marriage. The Dutch, who desired to control the Johor-Riau Empire, feared losing momentum because of the absence of mere regalia. They therefore ordered Timmerman Tyssen, the Dutch Governor of Malacca, to seize Penyengat in October 1822 and remove the royal regalia from Tengku Hamidah by force. The regalia was then stored in the crown prince's fort in Tanjung Pinang. Engku Puteri was reported to have written a letter to Van Der Capellen, the Dutch Governor in Batavia, about this issue. With the royal regalia in Dutch hands, Abdul Rahman was invited from Terengganu and proclaimed as the Sultan of Johor, Riau-Lingga and Pahang on 27 November 1822. Hence, the legitimate ruler of the Johor-Riau Empire was now Abdul Rahman, rather than the British-backed Hussein.
