World War II In World War II, collaborators with Nazi Germany were found in Stalin's Soviet Union and in other Western European countries, and Japanese collaborators operated in China. During
World War II, collaboration existed to varying degrees in German-occupied zones, ranging from government officials to celebrities and ordinary citizens. High-profile German collaborators included Dutch actor
Johannes Heesters or English-language radio-personality
William Joyce (the most widely known
Lord Haw-Haw).
France In France, a distinction emerged between the
collaborateur (collaborator) and the
collaborationniste (collaborationist). The term
collaborationist is mainly used to describe individuals enrolled in pseudo-Nazi parties, often based in Paris, who believed in
fascism or were anti-communists.
Collaborators on the other hand, engaged in collaboration for pragmatic reasons, such as carrying out the orders of the occupiers to maintain public order (policeman) or normal government functions (civil servants); commerce (including
sex workers and other women who had relationships with Germans and were called,
"horizontal collaborators"); or to fulfill personal ambitions and greed. Collaborators didn't necessarily believe in fascism or support Nazi Germany. With the defeat of the Axis, collaborators were often punished by
public humiliation, imprisonment, or execution. In France, 10,500 collaborators are estimated to have been executed, some after legal proceedings, others extrajudicially. British historian
Simon Kitson has shown that French authorities did not wait until
the Liberation to begin pursuing collaborationists. The
Vichy government, itself heavily engaged in collaboration, arrested around 2,000 individuals on charges of passing information to the Germans. They did so to centralise collaboration, ensure that the state maintained a monopoly in Franco-German relations and defend sovereignty so that they could negotiate from a position of strength. It was among the many compromises made by the Vichy government. Adolf Hitler gave Germans in France plentiful opportunities to exploit French weakness and maximize tensions there after June 1940. On June 25, 1940,
Jean Moulin, a French civil servant who served as the first President of the
National Council of the Resistance during World War II, was advised by German authorities to sign a declaration condemning an alleged massacre of Chartres civilians by French Senegalese troops. Moulin refused to collaborate, knowing that the bombing massacre was carried out by Germans. He was then incarcerated by the Germans, and cut his throat with glass to prevent himself from giving up information.
Low Countries In Belgium, collaborators were organized into the
VNV party and the
DeVlag movement in Flanders, and into the
Rexist movement in
Wallonia. There was an active collaboration movement in the Netherlands.
Norway (far right) and
Jonas Lie inspect the
Norwegian Legion Vidkun Quisling (1887–1945), a major in the Norwegian Army and former
minister of defence. He became minister-president of Norway in 1942, and attempted to Nazify the country, but was fiercely resisted by most of the population. His name is now synonymous with a high-profile government collaborator, now known as a
Quisling. The main collaborationists in East Yugoslavia were the German-puppet Serbian
Government of National Salvation established on the
German-occupied territory of Serbia, and the Yugoslav royalist
Chetniks, who collaborated tactically with the Axis after 1941.
Poland Collaboration in Poland was less institutionalized than in some other countries and has been described as marginal, a point of pride with the Polish people. However, the Soviet Union did find some individuals who would work with them, and this is demonstrated notably by the
Lublin government set up by the Soviets in 1944 that operated in opposition to the
Polish government-in-exile.
Vietnam Vietnamese emigres and expatriates living in France gained inspiration from the Nazi occupation in the country. These people believed in many European nationalist ideas at the time — these being a belief in an organic ethnocultural national community and an authoritarian corporatist state and economy. At the time Vietnamese feared that colonialism had "systematically destroyed all elements of social order ... which would have led the intellectual elite to oppose the bolshevization of the country." When German forces invaded France in May 1940 amid World War II, the French military and government saw a collapse. In addition, six to ten million people were forced to become refugees. The political response was then provoked by the Vietnamese in the country. France also had a group of Vietnamese students and professionals in Paris called the
Amicale annamite. They expressed a heavy dislike for French colonial rule without moving forward with any explicit ideological agenda. Their motives were expanded in 1943, with the addition of wanting to improve the situation of Vietnamese soldiers interned as POWs. This included improvements in conditions at camps, better food, health care, education, and vocational training., known as
Tokyo Rose, was tried for treason after World War II for her broadcasts to American troops.
1945–present More recent examples of collaboration have included institutions and individuals in
Afghanistan who collaborated with
Soviet forces during the
Soviet–Afghan War until 1989 and individuals in
Iraq and Afghanistan recruited by the
Coalition of the Willing. In 2014 during the
occupation of Crimea and ongoing
War in Donbas, some Ukrainian citizens collaborated with
Russian forces.
Israeli–Palestinian conflict In
Palestinian society, collaboration with
Israel is viewed as a serious offence and social stain and is sometimes punished (judicially or extrajudicially) by death. In addition, during the period of 2007–2009, around 30 Palestinians have been sentenced to death in court on collaboration-related charges, although the sentences have not been carried out. Police said it was unlikely that such a young boy would have been recruited as an informer. leading Hamas to describe them as "traitors". As of June 2025, the Popular Forces control aid routes and territory in eastern
Rafah. They acknowledged that they collaborate with Israel. On 4 December 2025, Yasser Abu Shabab was reportedly killed by unknown Palestinian gunmen near
Rafah. The
Israeli Army Radio reported that Abu Shabab and a senior commander of the group
Ghassan Duhine were wounded in the ambush.
War against the Islamic State Governments,
non-state actors, and private individuals cooperated and gave assistance to the
Islamic State of Iraq and the Levant (ISIL or ISIS) during the
Syrian Civil War,
Iraqi Civil War, and
Libyan Civil War.
Russian invasion of Ukraine The Ukrainian government has had broad support from its population, but support for Russia within Ukraine gained prevalence in the Donbas region during the years of Russian occupation. The Ukrainian government has since compiled a "registry of collaborators." It says that pro-Russian collaborators have acted as spotters to assist Russian shelling. Anti-collaboration laws were enacted by Ukrainian President
Volodymyr Zelenskyy after the invasion started, with offenders facing 15 years in prison for either collaborating with Russian forces, making public denials about Russian aggression or supporting Russia. == See also ==
