English summary: In the 1960s, West Germany experienced a process of change in civil society. One of the progresses in the context of increasingly global economic and political relations was the growing awareness of external problems and developments. This trend was supported by the student movement of 1968. Not only the Third-World-Movement of the 1970s but also later founded NGO's are rooted in the transnational solidarity of 1968. The demand of the students for worldwide political and social justice started as an ideational and publicly demonstrated solidarity and led to cross-border motion and active involvement. The author describes the constitutive factors of the rise of a Third-World-Solidarity in West Germany. She shows that several influences were significant for the dynamics of this protest field: Historical motives, international events and role models, intercultural exchange and an international avant-garde played an important part, as well as the correlation between students, critical representatives of the protestant church and the new ecumenical movement. Together with similar goals, the participation of Christians in the German student movement was one of the elements they shared with leftist protests in other countries, for example in Latin America. German description: Die 60er-Jahre bedeuteten fur die Bundesrepublik einen zivilgesellschaftlichen Wandel. Vor dem Hintergrund internationaler politischer Ereignisse und wirtschaftlicher Entwicklungen weitete sich der Blick uber die eigenen Grenzen hinaus, was der Internationalismus der 68er-Bewegung noch verstarkte. Die Forderung der Studenten nach globaler politischer und sozialer Solidaritat fand ihren Ausdruck zunachst in ideeller, offentlichkeitswirksam inszenierter Verbundenheit und mundete in einem grenzuberschreitenden Aufbruch. Die Autorin untersucht nicht nur die Entstehung dieser studentischen Dritte-Welt-Solidaritat, die konstitutiv fur die Dritte-Welt-Bewegung der 70er-Jahre und spaterer NGOs war. Sie zeigt auch, dass fur die Dynamik des Protestfeldes die Wechselwirkung zwischen Studenten, gesellschaftskritischen Vertretern der protestantischen Kirche und der neuen okumenischen Bewegung von Bedeutung war - neben vergangenheitsbezogenen Motiven, internationalen Kultbildern, einer internationalistischen Avantgarde und transnationalen Begegnungen.
