in Antrea, he issued one of his famous Sword Scabbard Declarations, in which he said that he would not "sheath my sword before law and order reigns in the land, before all fortresses are in our hands, before the last soldier of Lenin is driven not only away from Finland, but from White Karelia as well". During the Continuation War, Mannerheim gave the second Sword Scabbard Declaration. In it, he mentioned "the Great Finland", which brought negative attention in political circles. During the Continuation War, Finland occupied the most comprehensive area in its history. Many people elsewhere, as well as Finland's right-wing politicians, wanted to annex East Karelia to Finland. The grounds were not only ideological and political, but also military, as the so-called three-isthmus line was considered easier to defend. Russians and Karelians were treated differently in Finland, and the ethnic background of the country's Russian-speaking minority was studied to determine which of them were Karelian (i.e., "the national minority") and which were mostly Russian (i.e., "the un-national minority"). The Russian minority were taken to concentration camps so that they would be easier to move away. In 1941, the government published a German edition of Finnlands Lebensraum, a book supporting the idea of Greater Finland, with the intention of annexing Eastern Karelia and Ingria. Finland's eastern question During the Continuation War's attack phase in 1941, when the Finns hoped for a German victory over the Soviet Union, Finland began to consider what areas it could get in a possible peace treaty with the Soviets. The German objective was to take over the Arkhangelsk–Astrakhan line, which would have allowed Finland to expand to the east. A 1941 book by professor Jalmari Jaakkola, titled Die Ostfrage Finnlands, sought to justify the occupation of East Karelia. The book was translated into English, Finnish, and French, and received criticism from Sweden and the United States. The Finnish Ministry of Education established the Scientific Committee of East Karelia on 11 December 1941 to guide research in East Karelia. The first chairman of the commission was the rector of the University of Helsinki, Kaarlo Linkola, and the second chairman was Väinö Auer. Jurists worked to prepare international legal arguments for why Finland should get East Karelia. Motivations The motives of the Greater Finland idea are a subject of disagreement. Some supported the idea out of a desire for wider cultural cooperation. Later, however, the ideology
