Millions of East Germans had moved to the West before the Berlin Wall was erected in 1961, and some escaped in a successful "Republikflucht" attempts also afterwards. All East Germans were automatically entitled to receive a West German passport, but players who had caps for the DFV, like Norbert Nachtweih and Jürgen Pahl who fled in October 1976 at a U21-match in Turkey, were ineligible for international competition for the DFB due to FIFA rules. Lutz Eigendorf had escaped to the West in 1979 and died in 1983 in a mysterious car crash in which East German Stasi agents were involved.
