Danylo Lavrentiyovych Shumuk (30 December 1914 – 21 May 2004) was a Ukrainian political activist who served a total of 42 years imprisoned by three different states, Second Polish Republic, Nazi Germany and Soviet Union.

The representatives of the exiled government of the Ukrainian People's Republic fared poorly during Polish-Soviet War where they formed a late alliance with Poland and supported the latter's unsuccessful Kiev offensive.

In 1934, he was arrested by the Polish police and held in jail in Kovel until he was sentenced in 1935, to an eight-year term for his role in the underground Communist Party of Western Ukraine.

A secret appendix to the pact outlined a plan to divide Poland and Eastern Europe into Soviet and German spheres of influence.

Initially, the Soviet rule gained much support of the non-Polish population largely alienated by the nationalist policies of the Second Polish Republic.

During the round of repressions that followed the Soviet takeover, Danylo's older brother Anton, who worked for the Polish National Railway was arrested as an "enemy of the people."

When Germany attacked the Soviet Union, the work camps were transformed into Red Army Penal military units,[2] which were usually given the most dangerous assignments and were considered expendable.
