The organisation was fined in 1987 for "causing offence" to former Chancellor Willy Brandt, in their condemnation of what they saw as his appeasement policies towards communism.
One the weekend of 12–13 August 1989, Die Deutschen Konservativen held a vast anti-communist rally at Mölln, near Lübeck, with a procession of torchlit boats down the local canal, each carrying flags of the 'lost provinces' (Silesia, East Prussia, Danzig, Sudetenland, Pomerania, etc.)
with a large barge in the receiving lake holding visiting dignitaries from all over Europe, including a delegation from the UK's Western Goals Institute, who made inflammatory anti-communist speeches.
Some 20,000 people gathered for the demonstration, which ended with a huge march at midnight, led by the flags of the 'lost provinces' to the ancient town centre where a further closing speech was made by Heinrich Lummer.
