God, unmediated by Brahmin priests and rituals, through individual devotion (stemming from the Bhakti movement), chanting Bhajans, or hymns, as well as through yoga. Charitable service was also promoted. The Ramakrishna Mission in Singapore set up a home for boys from troubled homes, while the Sree Narayana Mission set up a home of the destitute elderly. Another social reform movement was the Self-Respect Movement, which emerged in Tamil Nadu in the 1920s to liberate Dravidian people, and especially Adi Dravidas and lower caste Tamils from what was seen as Brahmin oppression. This movement sought inspiration from Tamil history and culture. In Singapore, groups like the Tamil Reform Association were inspired by this movement. They imported publications from India that promoted the movement, and they also hosted visiting leaders of the Self-Respect Movement from Tamil Nadu when they visited Singapore. The Singapore groups focussed on moral, social and religious reform. For example, they campaigned against caste distinctions and alcohol abuse. These groups also promoted the use of the Tamil language, and the development of Tamil literature in Singapore, through the establishment of Tamil newspapers and schools. They were also involved in the union activism, especially in those work sectors dominated by Tamils. Tamil-educated journalists and teachers were at the forefront of this movement. Leaders like Thamizhavel G. Sarangapani were especially instrumental in championing the rights of Tamils and Indians, by encouraging Indians to register for Singapore citizenship in the 1950s and by campaigning to make Tamil one of Singapore's official languages. 1915 Singapore Mutiny The 1915 Singapore Mutiny, also known as the 1915 Sepoy Mutiny, was an incident concerning 850 Indian Army soldiers who mutinied against their British superiors on 15 February 1915 in Singapore, as part of the 1915 Ghadar Conspiracy (not to be mistaken for the Indian Mutiny of 1857).

In general, the mutiny was restricted to Muslim soldiers, and did not involve the wider Indian population in Singapore. While the mutiny was a significant event in
