The German Federal Office for the Protection of the Constitution between 1992 and 2006 said that the Republicans were a "party with partially extreme-right tendencies" although the Republican leadership did rebuff an electoral alliance with more openly extreme-right parties such as the National Democratic Party of Germany, losing members to these more successful parties. The Republicans' strongholds tended to be in relatively affluent South Germany rather than the more economically depressed Eastern Germany where the more radical right-wing parties tended to do well.
