The Karelian question or Karelian issue (Finnish: "Karjala-kysymys" ) is a dispute in Finnish politics over whether or not to try to regain control over Finnish Karelia and other territories ceded to the Soviet Union in the Winter War and the Continuation War.
 Despite the name "Karelian question", the term may refer also to the return of Petsamo, ceded parts of Salla and Kuusamo, and four islands in the Gulf of Finland.
 Sometimes the phrase "debate on the return of the ceded territories" ("luovutettujen alueiden palautuskeskustelu") is used.
 The Karelian question remains a matter of public debate rather than a political issue.

This article presents a partial list of the most prominent Nazi German concentration camps set up across Europe during the course of World War II and the ensuing Holocaust.
 A more complete list drawn up in 1967 by the German Ministry of Justice names about 1,200 camps and subcamps in countries occupied by Germany, while the Jewish Virtual Library writes: "It is estimated that the Germans established 15,000 camps in the occupied countries."
 The concentration camps are not to be confused with the extermination camps which were designed and built exclusively to kill prisoners on a massive scale immediately upon arrival.
 The extermination camps of Operation Reinhard such as Belzec, Sobibór and Treblinka served as "death factories" in which German SS and police murdered nearly 2,700,000 Jews either by asphyxiation with poison gas or by shooting.
 Meanwhile, the concentration camps listed herein served primarily as detention and slave labor exploitation centers.
 Most of them were destroyed by the Germans in an attempt to hide the evidence of war crimes and crimes against humanity; nevertheless tens of thousands of prisoners sent on death marches were liberated by the Allies afterward.
East Karelian concentration camps were special internment camps in the areas of the Soviet Union occupied by the Finnish military administration during the Continuation War.
 These camps were organized by the armed forces supreme commander Carl Gustaf Emil Mannerheim.
 The camps were intended to hold camp detainees for future exchange with the Finnic population from the rest of Russia.
 The mortality rate of civilians in the camps was high due famine and diseases.
Mannerheimintie (Swedish: "Mannerheimvägen" ), named after the Finnish military leader and statesman Carl Gustaf Emil Mannerheim, is the main street of Helsinki, Finland.
 It was originally named Heikinkatu (Swedish: "Henriksgatan" ), after Robert Henrik Rehbinder, but was renamed after the Winter War.
 The change of name was also suitable due to Mannerheim having paraded in along that road during the Finnish Civil War (1918), after German forces allied with Mannerheim's Finnish forces had retaken the city.
 That event is also portrayed in the landmark statue of Mannerheim sitting horseback.
 The statue is located along the Mannerheimintie just outside the modern arts museum Kiasma.
The Karelian hot pot (British) or Karelian stew (US) ("karjalanpaisti" in Finnish) is a traditional meat stew originating from the region of Karelia.
 It is commonly prepared using a combination of pork and beef, but lamb can also be used.
 Along with the Karelian pasties ("karjalanpiirakat"), it is the most widely recognised Karelian food in Finland.
 In 2007, it was selected as the national dish of Finland by the readers of the Finnish tabloid Iltalehti.
 In similar poll organized by the ELO Foundation for the Promotion of Finnish Food Culture in cooperation with the Central Union of Agricultural Producers and Forest Owners MTK and the Finnish Ministry of Agriculture and Forestry in autumn 2016, Karelian hot pot took second place, losing to rye bread.
The 4th Air and Air Defence Forces Command was a formation of the Russian Air Force.

 The command became the 4th Air and Air Defence Forces Army again on 1 August 2015.
Baron Carl Gustaf Emil Mannerheim (] ; 4 June 1867 – 27 January 1951) was a Finnish military leader and statesman.
 Mannerheim served as the military leader of the Whites in the Finnish Civil War, Regent of Finland (1918–1919), commander-in-chief of Finland's defence forces during World War II, Marshal of Finland, and the sixth president of Finland (1944–1946).
Finnish military ranks form a system that incorporates features from Swedish, German, and Russian armed forces.
 In addition, the system has some typically Finnish characteristics that are mostly due to the personnel structure of the Finnish Defence Forces.
 The ranks have official names in Finnish and Swedish languages and official English translations.
 The Swedish forms are used in all Swedish-languages communications in Finland, e.g. in Swedish-speaking units of Finnish Defence Force.
 The system of ranks in the Swedish Armed Forces is slightly different.
Forest Guerrillas (Finnish: "Metsäsissit" ) was a Finnic resistance movement formed by some of the inhabitants of the parishes of Repola and Porajärvi in addition to several White Guard volunteers after their territory was ceded to Bolshevist Russia in the Treaty of Tartu of 1920.
 The conflict is known as the East Karelian Uprising.
 The 2,000 "metsäsissi" forces managed to capture large parts of East Karelia during their rebellion against their Russian rulers in 1921, aiming to unite these areas with the newly formed Republic of Finland.
 Ultimately, however, in 1922 the rebel forces withdrew into Finland.
