In the late nineteenth and early twentieth centuries, tens of thousands of Sikhs emigrated from Punjab to Southeast and East Asia to purse a better livelihood. At the same time, the Singh Sabha Movement was gradually gaining momentum in Punjab, strengthening the Sikh identity. Furthermore, Sikh soldiers and policemen were deployed widely in Asia to safeguard the interests of the British Empire. This chapter argues that the three seemingly irrelevant historical events (the modern Sikh diaspora, the Singh Sabha Movement, and the Indian expedition during the Boxer Uprising in China) were essentially interrelated. The convergent point of these moments was the erection of a Sikh temple (gurdwara) on Queen’s Road East, Wanchai, Hong Kong Island, in 1902. Taking this event as a case study, this chapter seeks to explore the Singh Sabha Movement through the lens of the Sikh diasporic network and the imperial network. It also unveils the Indian face of the British Empire by the turn of the twentieth century, when Indians, rather than the British, were the protagonists and engineers.
