Constructing an expansive historical archive, Ballantyne draws on film, sculpture, fiction, and Web sites, as well as private papers, government records, journalism, and travel narratives. He proceeds from a critique of recent historiography on the development of Sikhism to an analysis of how Sikh identity changed over the course of the long nineteenth century. Ballantyne goes on to offer a reading of the contested interpretations of the life of Dalip Singh, the last Maharaja of Punjab. He concludes with an exploration of bhangra, a traditional form of Punjabi dance that diasporic artists have transformed into a globally popular music style. Much of bhangra's recent evolution stems from encounters of the Sikh and Afro-Caribbean communities, particularly in the United Kingdom. Ballantyne contends that such cross-cultural encounters are central in defining Sikh identity both in Punjab and the diaspora.
