While post-war optimism and a global push for decolonisation created an environment where myriad communities felt a palpable sense of possibility for bringing their aspirations of nationhood to life, many of these desires were unfulfilled. Imagining Malaya is an exploration of one of those many imagined nations that never came to be. It narrates a series of seemingly disparate and contradictory political acts by the Peranakan Chinese -- a creolised community borne of intermarriage between the earliest Chinese migrants to the region and indigenous Malays -- in the post-World War II period to demonstrate that the community were, in fact, seeking to bring to life a cosmopolitan, inclusive, and multi-ethnic imagination of the Malay(si)an nation. Engaging in a critical re-examination of the intertwined processes of decolonization and nation-making, Imagining Malaya provides an alternative reading of Malay(si)a's path to merdeka (independence) from the perspective of the Peranakan. It narrates how a once powerful community at the centre of Malay(si)an politics and society came undone by their attempts to present an alternative imagination of the nation which challenged the ethnocentrism that came to dominate the country's political life. Rewriting the Peranakan into the centre of Malaysia's national story rather than its periphery is a parable on the complexities and pitfalls of attempting to forge a representative nation-state from a multi-ethnic society during the transition between colony and nation. By bringing the Peranakan imaginary of the nation to life, Bernard Z. Keo makes a case for how studying nations that were unrealized can reveal just as much as investigating those that were.
