On 17 June 1953, around one million people took to the streets in East Berlin and around 700 other places in the GDR. The reason was to protest against an increase in labour standards. However, the demonstrators also made political demands, for example for improved living conditions, free elections and the unification of Germany. The GDR leadership and Soviet occupation troops used violence against the demonstrators and put an end to the protests. At least 55 people were killed, 15,000 others were arrested and around 1,500 of them were later sentenced.
