This book examines the development and issuance of the Balfour Declaration, the document that set the stage for the creation of the state of Israel, within its global setting. The heart of the book demonstrates that the Declaration developed and contributed to a juncture in a global dialogue about the nature and definition of nation at the outset of the twentieth century. Embedded in this examination are gendered, racial, nationalistic, and imperial considerations. The work posits that the Balfour Declaration was a specific tool designed by the manipulation of these ideas. Once established, the Declaration helped, and hindered, established imperial powers like the British, nascent imperial powers like the Japanese and Indians, and emerging nationalist movements like the Zionists, Irish, Palestinians, and East Africans, to advocate for their own vision of national definition.
