This article examines the role solidarity magazines played for the first generation of global Palestine activists. Through an analysis of Scandinavian magazines of the late 1960s and early 1970s, and microhistories of the first generation of solidarity activists in Denmark, Norway, and Sweden based on interviews, memoirs, novels, and letters, this article examines how the first Palestine committees and the foundational notions of the Palestinian cause were formed. This article argues that the solidarity magazine became a central forum for the co-creation of Palestine solidarity between Palestinians and their sympathizers. Viewing solidarity as a result of joint political and intellectual labor gives agency to solidarity as a third space between national solidarity movements and Third World liberation movements. By taking this approach, this article reads magazines as an aperture into the first iteration of Palestine as a global cause.
