Kreuzberg stages an alternative celebration marking International Workers’ Day on 1 May 1987. What begins as a peaceful event during the day descends into rioting that night. A supermarket burns to the ground, whole streets are set on fire and 250 police officers are injured. The next morning, parts of Kreuzberg lie almost in ruins. It is the start of a cycle that will see the district erupt into violence on 1 May for many years to come.
