such as freedom of movement to be limited in case of a state of emergency. Leading up to the passing of the laws, there was fierce opposition to them, above all by the FDP, the rising German student movement, a group calling itself ("Democracy in a State of Emergency") and the labour unions. Demonstrations and protests grew in number, and in 1967 the student Benno Ohnesorg was shot in the head by a policeman. The press, especially the tabloid newspaper, launched a campaign against the protesters. By 1968 a stronger desire to confront the Nazi past had come into being. In the 1970s environmentalism and anti-nationalism became fundamental values among left-wing Germans. As a result, in 1979 the Greens were able to reach the 5% minimum required to obtain parliamentary seats in the Free Hanseatic City of Bremen state election, and with the foundation of the national party in 1980 developed into one of the most politically successful green movements in the world. Another result of the unrest in the 1960s was the founding of the Red Army Faction (RAF). The RAF was active from 1968, carrying out a succession of terrorist attacks in West Germany during the 1970s. Even in the 1990s, attacks were still being committed under the name RAF. The last action took place in 1993, and in 1998 the group announced it was ceasing activities. In the 1969 election, the SPD gained enough votes to form a coalition government with the FDP. SPD leader and Chancellor Willy Brandt remained head of government until May 1974, when he resigned after the Guillaume affair, in which a senior member of his staff was uncovered as a spy for the East German intelligence service, the . However the affair is widely considered to have been merely a trigger for Brandt's resignation, not a fundamental cause. Instead, Brandt, dogged by scandal relating to alcohol and depression as well as the economic fallout of the 1973 oil crisis, almost seems simply to have had enough. As Brandt himself later said, "I was exhausted, for reasons which had nothing to do with the process going on at the time". Finance Minister Helmut Schmidt (SPD) then formed a government, continuing the SPD–FDP coalition. He served as Chancellor from 1974 to 1982. Hans-Dietrich Genscher, a leading FDP official, was Vice Chancellor and Foreign Minister in the same years. Schmidt, a strong supporter of the
