While each author has contributed according to their expertise, they also reflect on how John's ideas and approaches continue to stimulate new work in disparate fields. Touching on the experience of empire in Europe, Africa, Asia and Australasia, the authors have engaged with concepts from across Darwin's writings, including his earlier work on decolonisation, 'decline', and 'the dynamics of territorial expansion'. As such, the work in this volume operates across a number of different scales of analysis: from case studies of transnational communities, state formation and military intervention, to imperial politics, inter-imperial comparison, and global historical frameworks.

The chapters in this book were originally published as a special issue of The Journal of Imperial and Commonwealth History.
