This was due to the Portuguese conquest of Malacca in 1511, and their attempt to control the spice trade. As the first base of European Christian trading in Southeast Asia, Malacca was surrounded by native Muslim states. Portuguese Malacca was under almost constant attack. They endured years of battles started by Malay sultans who wanted to get rid of the Portuguese and reclaim their land. The Sultan, Mahmud Shah made several attempts to retake the capital. At that time, a messenger came from King Tuk Sangar asking for help to attack the Portuguese in Malacca. Tuk Jayo rifle sent his armed forces, commanded by Panglima Kuntu, attacking Simpang Empat, on the island of Siapung Up (Serapung). At that time, the commander was very famous for his powerful navy, controlling Kuala Kampar. It is possible they sunk quite a few Portuguese ships. Years later, a messenger came from Aceh demanding that the Kingdom convert to Islam. Aceh's demands were rejected by Tuk Jayo rifle. But Aceh continued on an expedition to conquer the east coast of Sumatra and eventually sent much of the pepper through its own port. After Segati was lost, Tuk Jayo fled to the Petalangan Napuh, then to Kuantan. Traces of the conquest of Aceh can still be encountered with places named Rencong Aceh, Aceh Base, and Lubuk Aceh. In the following years, Segati established a new country by the name of Tambak, and then Langgam. Segati Kingdom is currently located in Langgam Segati Pelalawan. People here mostly live from farming, forestry and palm oil plantation. Acacia trees supply the raw material for paper. Segati forests are currently managed by PT. Siak Raya Timber (SRT) and also PT. Riau Andalan Pulp and Paper (RAPP), possibly illegally. Disputes are common between villagers and the RAPP, over land and tree planting in the area.
