On the occasion of the 150th anniversary of the first anti-authoritarian international, international meetings are being prepared in the Swiss Jura mountains. They will take place from July 19 to 23, 2023 - with an extension of a few days to allow time and space for spontaneous meetings. We are making this appeal to clarify the role of these meetings, that is to say our concrete motivations, as well as the way we wish to organize them.
