In order to reestablish the Turkish union that was undermined in Anatolia, Suleymanshah subdued the cities of Amasya, Niksar and Elbistan that were dominated by his brothers. The Byzantine emperor who benefited from these struggles indirectly set in motion from the coasts of the Black Sea. Suleymanshah obstructed these developments and made an agreement with the emperor. Then, he defeated Leon II, the Armenian king of Cilicia who had started to attack to the northern regions of Taurus mountains and captured some castles in that region. Then, he forced them to retreat to the south of the Taurus Mountains. Sultan levied a tribute on the Byzantine emperor and punished the Armenian kingdom. Then, he oriented towards the Eastern Anatolia and captured Malatya. On the other hand, he subdued Erzincan Mengucuk-ogullari and Artuk-ogullari principalities to his submission. In the year of 1202, Suleymanshah captured Erzurum and abolished the Saltuklu principality. Then, he became the neighbour of the Georgians. In the same year, Suleymanshah was defeated in the war with the Georgians that took place near Sarikamis. Then, he captured Ankara from the domination of Mes'ud. When he set off for his second military expedition to Georgia, he died in the place between Konya and Malatya (6th July 1204).
