This book comprises of the papers that were presented at the ILRIG 40th Anniversary Festival that was held at the end of 2023. The Festival was a celebration of ILRIGʼs 40 years and it looked at current and historical at-tempts to build working class power through popular education, self-organising and resistance. As such, the Festival brought together activists, support organisations, worker formations, feminist struggles, community organisations, progressive movements, academics and artists from southern Africa, Brazil, Kurdistan/Germany and Argentina to reflect, celebrate and deepen the experience of 40 years of struggles to build alternatives to capitalism, nation states and patriarchy.
