This chapter focuses on the British community in pre-war Hong Kong and explores how Britishness as a non-European identity translated to a colonial setting. Drawing from laws, social practices, and press debates, this chapter explores how white Britons viewed colonial British subjects and other non-British Europeans in Hong Kong. Many white Britons clearly saw ‘British’ as a racial category, and they worked hard to maintain the arbitrary boundary of the ‘British race’. But by the 1930s the latest, hostility towards other Europeans became visible as international relations deteriorated in Europe. Amidst talks of ‘Buy British’ and ‘Britons First’ were also vocal appeals to include colonial subjects as part of being British. Findings of this chapter uncovered in the British community in 1910–45 Hong Kong not only an increasingly inclusive attitude towards British subjects of colour, but also a determination to define Britishness as not only a race, but also a national identity.
