During World War I, Singapore remained relatively untouched by the global conflict, with the most notable local event being the 1915 mutiny by Muslim Indian sepoys stationed in the city. These sepoys, after hearing rumors of being deployed to fight against the Ottoman Empire, revolted against their British officers. This rebellion was influenced by the Ottoman Sultan Mehmed V. Reshad's declaration of jihad against the Allied Powers and his subsequent fatwa urging Muslims worldwide to support the Caliphate. The Sultan, considered the Caliph of Islam, held significant influence over global Muslim communities, especially those under British rule. In Singapore, the sepoys' loyalties were further swayed by Kasim Mansur, an Indian Muslim merchant, and local imam Nur Alam Shah. They encouraged the sepoys to obey the Sultan's fatwa and revolt against their British superiors, leading to the planning and execution of the mutiny.
