Sultan Sulaiman was succeeded by Tengku Alam Shah in 1938, using the title Sultan Hisamuddin Alam Shah.[1] In January 1942, following the Japanese occupation of Malaya, he was told to surrender his throne to his elder half-brother, Tengku Musa Eddin, whom the Japanese proclaimed as the new Sultan of Selangor, taking the title Sultan Musa Ghiatuddin Riayat Shah. Sultan Hisamuddin refused Japanese orders for him to work with them and stopped receiving the allowance awarded to him. Sultan Musa Ghiatuddin Riayat Shah was installed as the seventh Sultan of Selangor by the then Governor of Selangor, Lieutenant-General Shotaro Katayama in November 1943.
