Forced labour under German rule during World War II in the context of "Untermenschen"

The Holocaust (/ˈhɒləkɔːst/ HOL-ə-kawst), known in Hebrew as the Shoah (/ˈʃoʊə/ SHOH-ə; Hebrew: שּׁוֹאָה, romanized: Shoah, IPA: [ʃoˈʔa], lit. 'Catastrophe'), was the genocide of European Jews during World War II. From 1941 to 1945, Nazi Germany and its collaborators systematically murdered some six million Jews across German-occupied Europe, around two-thirds of Europe's Jewish population. The murders were committed primarily through mass shootings across Eastern Europe and poison gas chambers in extermination camps, chiefly Auschwitz-Birkenau, Treblinka, Belzec, Sobibor, and Chełmno in occupied Poland. Separate Nazi persecutions killed millions of other non-Jewish civilians and prisoners of war (POWs); the term Holocaust is sometimes used to include the murder and persecution of non-Jewish groups.

The Nazis developed their ideology based on racism and pursuit of "living space", and seized power in early 1933. Meant to force all German Jews to emigrate, regardless of means, the regime passed anti-Jewish laws, encouraged harassment, and orchestrated a nationwide pogrom known as Kristallnacht in November 1938. After Germany's invasion of Poland in September 1939, occupation authorities began to establish ghettos to segregate Jews. Following the June 1941 invasion of the Soviet Union, 1.5 to 2 million Jews were shot by German forces and local collaborators. By early 1942, the Nazis decided to murder all Jews in Europe. Victims were deported to extermination camps where those who had survived the trip were killed with poisonous gas, while others were sent to forced labor camps where many died from starvation, abuse, exhaustion, or being used as test subjects in experiments. Property belonging to murdered Jews was redistributed to the German occupiers and other non-Jews. Although the majority of Holocaust victims died in 1942, the killing continued until the end of the war in 1945.

The V-2 rocket (German: Vergeltungswaffe 2, lit. 'Vengeance Weapon 2'), with the development name Aggregat-4 (A4), was the world's first long-range guided ballistic missile. The missile, powered by a liquid-propellant rocket engine, was developed during the Second World War in Nazi Germany as a "vengeance weapon" and assigned to attack Allied cities as retaliation for the Allied bombings of German cities. The V2 rocket also became the first artificial object to travel into space by crossing the Kármán line (edge of space) with the vertical launch of MW 18014 on 20 June 1944.

Research of military use of long-range rockets began when the graduate studies of Wernher von Braun were noticed by the German Army. A series of prototypes culminated in the A4, which went to war as the V2. Beginning in September 1944, more than 3,000 V2s were launched by the Wehrmacht against Allied targets, first London and later Antwerp and Liège. According to a 2011 BBC documentary, the attacks from V-2s resulted in the deaths of an estimated 9,000 civilians and military personnel, while a further 12,000 laborers and concentration camp prisoners died as a result of their forced participation in the production of the weapons.

The Generalplan Ost (German pronunciation: [ɡenəˈʁaːlˌplaːn ˈɔst]; lit. 'Master Plan for the East'), abbreviated GPO, was Nazi Germany's plan for the settlement and "Germanization" of captured territory in Eastern Europe, involving the genocide, extermination and large-scale ethnic cleansing of Slavs, Eastern European Jews, and other indigenous peoples of Eastern Europe categorized as "Untermenschen" in Nazi ideology. The campaign was a precursor to Nazi Germany's planned colonisation of Central and Eastern Europe by Germanic settlers, and it was carried out through systematic massacres, mass starvations, chattel labour, mass rapes, child abductions, and sexual slavery.

Generalplan Ost was only partially implemented during the war in territories occupied by Germany on the Eastern Front during World War II, resulting indirectly and directly in the deaths of millions by shootings, starvation, disease, extermination through labour, and genocide. However, its full implementation was not considered practicable during major military operations, and never materialised due to Germany's defeat. Under direct orders from Nazi leadership, around 11 million Slavs were killed in systematic violence and state terrorism carried out as part of the GPO. In addition to genocide, millions more were forced into slave labour to serve the German war economy.

Prisoners of war during World War II faced vastly different fates due to the POW conventions adhered to or ignored, depending on the theater of conflict, and the behaviour of their captors. During the war approximately 35 million soldiers surrendered, with many held in the prisoner-of-war camps. Most of the POWs were taken in the European theatre of the war. Approximately 14%, or 5 million, died in captivity; out of these, 3 million fatalities were Soviets POWs, and one million, German POWs.

Early in World War II, Nazi Germany, overwhelmed by the number of POWs, released many, though some became used as forced labor. As the war progressed, POWs became strategic assets, increasingly used as forced labor, or considered an important leverage for reciprocal treatment. Within a few years of the war ending, most of POWs were repatriated, though notable exceptions persisted, with Axis POWs in Chinese and Soviet camps held into the 1950s.

Pope John Paul II (born Karol Józef Wojtyła; 18 May 1920 – 2 April 2005) was head of the Catholic Church and sovereign of the Vatican City from 16 October 1978 until his death in 2005. He was the first non-Italian pope since Adrian VI in the 16th century, as well as the third-longest-serving pope in history, after Pius IX and St. Peter.

In his youth, Wojtyła dabbled in stage acting. He graduated with excellent grades from an all-boys high school in Wadowice, Poland, in 1938, soon after which World War II broke out. During the war, to avoid being kidnapped and sent to a German forced labour camp, he signed up for work in harsh conditions in a quarry. Wojtyła eventually took up acting and developed a love for the profession and participated at a local theatre. The linguistically skilled Wojtyła wanted to study Polish at university. Encouraged by a conversation with Adam Stefan Sapieha, he decided to study theology and become a priest. Eventually, Wojtyła rose to the position of Archbishop of Kraków and then a cardinal, both positions held by his mentor. Wojtyła was elected pope on the third day of the October 1978 conclave, becoming one of the youngest popes in history. The conclave was called after the death of John Paul I, who served only 33 days as pope. Wojtyła adopted the name of his predecessor in tribute to him.

The Maquis (French pronunciation: [maˈki] ) were rural guerrilla bands of French and Belgian Resistance fighters, called maquisards, during World War II. Initially, they were composed of young, mostly working-class men who had escaped into the mountains and forests to avoid conscription into Vichy France's Service du travail obligatoire (STO; 'Compulsory Work Service') which provided forced labor for Germany. To avoid capture and deportation to Germany, they became increasingly organized into active resistance groups.

They had an estimated 25,000 to 40,000 members in autumn of 1943 and approximately 100,000 members in June 1944.
