Sultan Alaeddin Sulaiman Shah of Selangor
Sultan Alaeddin Sulaiman Shah (1863-1938) was the 5th Sultan of Selangor (1898-1938), 3 years after Selangor joined the Federated Malay States, a federation of 4 protected states — the other 3 states are Perak, Negeri Sembilan, and Pahang — in the Malay Peninsula established by the British colonial government. In 1905, Sultan Alaeddin built Istana Alam Shah and lived there for 35 years until his death in 1938.
2. Succession dispute: Sultan Alaeddin Sulaiman Shah's first 3 sons were Tengku Musa Eddin, Tengku Badar Shah, and Tengku Alam Shah. The first 2 sons were children by his royal consort, Tengku Ampuan Maharum binti Tengku Dhiauddin of the royal house of Kedah, while Tengku Alam Shah was by his commoner wife, Cik Puan Hasnah binti Pilong.
In 1920, Tengku Musa Eddin was appointed the Raja Muda of Selangor. However, in 1934, he was dismissed for alleged "misbehavior", at the instigation of Theodore Samuel Adams (1885–1961), the then British Resident of Selangor (1935-1937). Adams had accused Tengku Musa Eddin of being a spendthrift and a wastrel, with a penchant for gambling. (However, many Malays in Selangor believed that the real reason for Tengku Musa Eddin's dismissal was his refusal to follow Adam's orders.)
On 20 July 1936, Tengku Alam Shah was proclaimed Raja Muda of Selangor, in spite of Sultan Alaeddin pleading for the case of Tengku Musa Eddin. Sultan Alaeddin even went so far as to discuss the issue with the Secretary of State for the Colonies in London but all his efforts were in vain. (Malay customs dictate that the son of a royal wife takes precedence over the sons of other wives.)
Sultan Alaeddin Sulaiman Shah died on 31 March 1938 and 4 days later, Tengku Alam Shah was proclaimed the 6th Sultan of Selangor. Tengku Musa Eddin, the then Tengku Kelana Jaya Putera, presided over the ceremony with no ill feelings. more... at Chronology
