When Ralf was only a teenager, he and his father, an SPD member of the German Parliament, were arrested and sent to concentration camps for their anti-Nazi activities during the Nazi regime. One of the activities consisted of Dahrendorf distributing leaflets that were encouraging people not to join the regime. After this, his family moved to Berlin. In 1944, during the last year of the Second World War, he was arrested again for engaging in anti-Nazi activities and sent to a concentration camp in Poland. He was released in 1945.

Ralf Dahrendorf studied philosophy, classical philology, and sociology at Hamburg University between 1947 and 1952. He continued his academic research at the London School of Economics under Karl Popper as a Leverhulme Research Scholar in 1953–1954, gaining a PhD degree in sociology in 1956. At this early stage in Dahrendorf's academic career, he took an interest in Marxist theory and wrote his PhD thesis on Karl Marx's theory of justice. After completing his doctorate he returned to Germany, where he was a professor of sociology at Hamburg (1957–1960), Tübingen (1960–1964) and Konstanz (1966–1969) universities. He was one of the founders (1964) of the University of Konstanz.
From 1957 to 1959, Dahrendorf talked about "this ability to organize as the principle between quasi-groups and interest groups". Quasi-groups are defined as "those collectives that have latent identical role interests but do not experience a sense of "belongingness". Interest groups, on the other hand, "have a structure, a form of organization, a program or goal, and a personnel of members". The interest groups identity and sense of belonging are produced when people have the ability to communicate, recruit members, form leadership, and create a unifying ideology In 1960, he became a visiting professor of sociology at Columbia University in New York.
From 1967 to 1970, he was Chairman of the German Sociological Association (Deutsche Gesellschaft für Soziologie), resigning it when he took up his office at Brussels. Between 1976 and 1979 he led the educational sub-committee of the Benson Commission.

Dahrendorf decided to become a member of the Bundestag in 1969 during the time when Brandt formed his first SPD-FDP coalition government. After joining, he was appointed parliamentary secretary to the foreign minister. Because he was placed third on the ladder of command in the foreign ministry, he did not enjoy the experience. From 1969 to 1970 he was a member of the German parliament for the Free Democratic Party (the German liberals). During this period he was also a Parliamentary Secretary of State in the Ministry of Foreign Affairs. In 1970 he became a Commissioner in the European Commission in Brussels. He was dedicated to the EU as a guarantor of human rights and liberty.
In 1974, the BBC invited him to present the annual Reith Lectures. In this series of six radio talks, entitled The New Liberty, he examined the definition of freedom.
