Виленский край
On 11 November 1920, after Lithuania lost its capital Vilnius to the Żeligowski's Mutiny, the Rada of the Belarusian Democratic Republic signed a partnership treaty with Lithuania and relocated to Kaunas. That brought two centers of Belarusians activities to Kaunas but they were not inclined to cooperate. Their competences were divided: the ministry was in charge of Belarusian affairs inside the Lithuanian borders up to the demarcation line with Poland, while the Rada was in charge in Vilnius Region (i.e. between the demarcation line and the border drawn by the Soviet–Lithuanian Peace Treaty). That pushed the ministry into a secondary role as the Lithuanians cared more about the support Belarusians could provide in their territorial conflict with Poland over the Vilnius Region.
