This volume honours the remarkable life and legacy of ldris, who passed away in 2019 at the age of 93, after more than half a century of fighting for justice in its many forms – consumer rights, environmental protection, health, education, and the sovereignty of developing nations. In these pages, voices from across the world pay tribute to a man who redefined the art of resistance, refused compromise in the face of injustice, and whose principled activism bridged grassroots action, academic debate, and political resistance.
