Lying is inseparable from the totalitarian system. It was also omnipresent throughout the entire period of the communist system in Poland. It appeared already at the dawn of the installation of the Polish communist power, completely vassal to the Soviet Union by the establishment of the Polish Committee of National Liberation (PKWN) in July 1944.

Throughout the period of communist rule in Poland, every year the 22nd of July was a public holiday, celebrated on the anniversary of the establishment of the Polish Committee of National Liberation (PKWN). As well as being a statutory holiday, the communist authorities in Poland then attempted to organise celebrations often combined with the commissioning of many investments. For example, they launched Poniatowski Bridge in Warsaw (1946), the Palace of Culture and Science, and the 10th Anniversary Stadium (1955). Also, the communist constitution, written under the dictates of Joseph Stalin, was passed on 22 July 1952, and in many Polish cities streets and squares were called PKWN or 22 July ones. In 1949, even the nationalised chocolate factory, owned by the Wedel family since its inception in 1851, was renamed “the 22nd July Confectionery Plant, formerly E. Wedel”.

On 22 July 1944, the Moscow radio reported that it was on this day that the Polish Committee of National Liberation was formed in Chełm, and that on the same day it published a manifesto outlining its programme.

In fact, the PKWN was formed on 21 July not in Chelm, but in Moscow. The Soviet dictator Joseph Stalin himself decided on its formation and the people who became its members. The establishment of the PKWN, which was a puppet government completely subordinate to the Soviet Union, was a step towards the complete seizure of power in Poland by the communists, despite the fact that there was a legitimate Polish government in exile in London.

It was not until 27 July 1944 that a representative of the PKWN arrived in Chelm, having previously signed agreements in Moscow with the Soviet authorities, including the agreement on a common border, in which the PKWN relinquished to the Soviet Union the Polish Eastern Borderlands, which had been part of the Polish state before the outbreak of the Second World War.
