In the early hours of 1 September 1939, without declaring war on Poland, Germany attacked along the whole length of the border between the two countries. Artillery barrage laid down on a Polish military transit depot by Schleswig-Holstein, a German battleship, has become a symbolic opening of the Second World War.

On Thursday, June 28th, 1956, at 6:30am, the main factory siren was sounded in the Joseph Stalin Poznań Metal Works (ZISPO, then called the Hipolit Cegielski Metal Works). For workers present on site, distressed with their economic situation and disappointed with both deteriorating working conditions and their demands being ignored by the authorities, it was a signal to start a demonstration.
The events of March 1968 were multi-faceted; in the space of a few weeks, several completely different and often unrelated incidents dovetailed with each other. In that light, when talking about the genesis of the March 1968 events, it is necessary to mention a series of diverse proceedings.

Independence movements were also established in the Soviet Union, mainly in Lithuania, Latvia, Ukraine, Estonia and Georgia. After a summer wave of strikes, talks of a Round Table with part of the opposition were announced in Poland.
