The first step towards the university was taken on 23 February 1959 with the decision of the city council to launch a university project, which was followed in 1970 with the "Memorandum establishing the University of Oldenburg" from the Minister of Culture of Lower Saxony. The university was finally founded in 1973. Enrollment and teaching started in the summer semester of 1974, with an education curriculum for 2,400 students. In 1991, the university was officially named after pacifist, writer and Nobel laureate Carl von Ossietzky, having been denied to take on his name by previous (both left-leaning and right-leaning) state governments. That same year, the number of students passed the mark of 10,000. The eleven departments of the university were reorganized into five faculties in 2002. By the end of 2011, there were about 11,325 students.
