The idea of an international marxist-feminist conference was originally brought into being, and was since then continuously organized, by the feminist section of the Berliner Institut of Critical Theory (Inkrit) around the German sociologist and philosopher Frigga Haug. It was held in Berlin for the first time in 2015, followed by an increasingly international second congress in Vienna in 2016, and the third one in Lund (Sweden) in 2018.

The 4th International Conference will be held in Bilbao (Bizkaia Aretoa), in November (11, 12, 13) 2021. This Confernce will be organized and funded by Transform! Europe and the University of the Basque Country, along with Iratzar Foundation, Bilbo-Barcelona Critical Theory Group (BIBA CT), Berliner Institut für Kritische Theorie (Inkrit) and Roxa Luxemburg Foundation and ParteHartuz, among others (which will be made public in the following months).
