Less than two decades later in 1717, Raja Kechil would assemble a fleet from Minangkabau and succeed temporarily in ousting Sultan Abdul Jalil's successor Sultan Sulaiman and gain the Johor Sultanate, basing his legitimacy on the claim that he was the post-humous son of Sultan Mahmud Shah II . However, Bugis mercenaries that assisted him in this campaign changed sides and he was eventually forced to flee to Siak, where he founded Siak Sultanate.
