In 1718, "Raja Kecil" succeeded in conquering the Johor Sultanate, at the same time crowning himself as the Sultan of Johor with the title "Yang Dipertuan Besar Johor". But in 1722, a rebellion led by Raja Sulaiman who is the son of the former Sultan Abdul Jalil Shah IV who also demanded the right to the throne of Johor. With the help of Bugis mercenaries, Raja Sulaiman then succeeded in seizing the throne of Johor, and established himself as the ruler of Johor in Peninsular Malaysia, crowning himself as Sultan Sulaiman Badrul Alam Shah of Johor, while "Raja Kecil" moved to Bintan and in 1723 established a new government center on the bank of the Siak River with the name Siak Sri Inderapura. While the center of the Johor government which had been around the estuary of the Johor River was abandoned, and became the "status quo" of each of the warring rulers. Whereas the claim of "Raja Kecil" as the legitimate heir to the throne of Johor, was recognized by the Orang Laut community. The Orang Laut is a Malay sub-group that resides in the Riau Islands region that stretches from east Sumatra to the South China Sea, and this loyalty continues until the collapse of the Siak Sultanate.
