The aim of InterSol research project is to study the political mobilization in Europe and beyond during the interwar period within the context of global history. The articulation and organization of the international solidarity are studied and analyzed from the perspective of the agents as well as of the networks. Project consists of several subprojects that share the analytical and thematic referential frame. The reference frame of the subprojects consists of analyzing the different research objects from a progressive perspective: the outcomes of the activities and aspirations within the projects are not given but studied through a profound analysis of different opportunities that were possible and worth the effort during that period of time. The theoretical grounds of the project are founded in the application of the postcolonial discourses that offer the angle of approach for understanding the international solidarity, possibilities and limitations of the utopian ideals and the complex of problems that occur between the political consciousness of the minority and the actions of the ’masses’. The postcolonial discourse that bursts from the dominating Eurocentric perspective during the interwar period, ”the European/ Western dilemma”, as well as the progressive attempt in historical research open up an opportunity to deeper knowledge an analyses of the history of the 1920’s and 1930’s. The research project focuses on the following organisations: – International Trade Union Committee of Negro Workers (Holger Weiss) – League Against Imperialism (Fredrik Petersson) – Workers’ International Relief (Kasper Braskén) – International of Seamen and Harbour Workers (Holger Weiss)
