This collection came out of the conference ‘1917: Revolution, Intervention and International Law(s)’ held at Melbourne Law School in August 2017. We would like to thank all of the speakers and participants at the conference, for their efforts in thinking through the concerns of the conference and this volume, and for the stimulating discussion and exchange that ensued. Our gratitude is due to the contributors to this volume for the brilliant and considered set of chapters they provided. It has been our pleasure to work with you all. The conference was able to take place as a result of the generous support of the Australian Research Council through Anne Orford’s Laureate Fellowship and Melbourne Law School’s International Collaboration Fund. Our warm thanks go to Jack Stanovsek and Wendy Chen for their extremely capable and diligent efforts in making the event possible. Wendy Chen also provided editorial assistance for this book, for which we are grateful.
