Thousands of socialist supporters participated in the Luxemburg-Liebknecht demonstration in Berlin on Sunday, commemorating the 100th anniversary of the 1919 executions of Rosa Luxemburg and Karl Liebknecht.
Holding red flags and chanting slogans, the demonstrators marched from Frankfurter Tor through Berlin’s streets before laying carnations at the socialists' monument in Friedrichsfelde Central Cemetery.
"I think those people had a critique of capitalism and they were also intellectuals, and they were coming up with ideas that are still quite valid today," said one of the supporters.
Luxembourg and Liebknecht were both shot dead on January 5, 1919 by German Freikorps soldiers in Berlin.
Since the creation of the German Democratic Republic, socialist and communist sympathisers have held an annual memorial march in honour of communist and socialist figures on the second Sunday of January each year.
