Today, we commemorate #BlackRibbonDay. It was set on the anniversary of the Ribbentrop-Molotov Pact signing, which tore apart Central and Eastern Europe between Nazi Germany and the Soviet Union. We honour those who died under Soviet and Nazi German terror. | Embassy of the Republic of Poland in London

The Soviet invasion of Poland on September 17th 1939, was a direct result of the Ribbentrop-Molotov Pact, signed between Germany and the Soviet Union on 23 August, 83 years ago today. A secret protocol that cut the continent into two spheres of influence split between two totalitarian systems – that of Nazi Germany and that of the Soviet Union. | British Poles
