He ascended to the throne at the age of 17 after the death of his father in May 1906. It is notable that he also became the first Sultan of Brunei to speak English. The responsibility of the Sultan was in the hands of the Majlis Pemangku Raja (Council of Regency). During his reign, he aimed to encourage new developments in agriculture, medicine, and education. Jamalul Alam oversaw several major events such as the first discovery of crude oil was first discovered in the country but not before major oil strikes were made in Seria in 1927. Moreover, his reign was in charge of Brunei during its most impoverished state.

In 1909, he relocated his residence on land, and later encouraged Chinese to settle in Brunei for commercial skills. It was only on 15 May 1918 that he was crowned as sultan. Jamalul Alam was convinced by the bendahara (vizier) to signed a petition to change 5 points to the 1905 treaty. It was also during his reign that Islamic Law was officially introduced in the country. This was known as Mohammedan Laws Enactment. It was introduced in 1912, replacing the Kanun Brunei. Then in 1913, the Marriage and Divorce Act was introduced.

With the introduction of the Residential System in Brunei in 1906, all the executive power, except in matters of religion and tradition, was transferred from the Sultan to the Resident. It was only until 1918, he was crowned Sultan of Brunei. In 1922, he moved from Istana Kampong Ayer to Istana Majlis. That same year, a band of traditional musicians was sent to Singapore as attendants to the Sultan.
