The Turkish community form the largest ethnic minority in Germany. Many are descendants of the guest workers who arrived when large-scale migration of Turkish citizens to West Germany was encouraged during the 1960s and 1970s.

The rule changed in 2000 and gave citizenship by birth if one parent possesses German citizenship or if one parent has been a legal resident in Germany for eight years.
