May Day in Kreuzberg refers to the street fairs and demonstrations organized by leftist and extreme-left groups in Berlin's borough Kreuzberg on the 1st of May. Specifically, this term may refer to the 1st of May 1987, when particularly severe unrest hit Kreuzberg and the Berlin police had to retreat entirely from district SO 36 (a part of Kreuzberg) for several hours. Since then, Autonome (socialists) and Anti-Fascist groups have been organizing one or more so-called "Revolutionary 1st of May Demonstrations" almost every year. There can be riots in the night before or after the 1st of May.
