Suwałki Governorate
In 1837 Augustów Governorate was established in the territories of the Congress Poland, a state in personal union with Russia. Lithuanian Suvalkija was included into this governorate. After the January Uprising, Augustów Governorate was split into Suwałki Governorate and Łomża Governorate (see Administrative division of Congress Poland). This way most of the present-day territory of Lithuania fell into three governorates (Vilna, Kovno, and Suwałki). Two more governorates included some small Lithuanian territories. In 1819 a narrow coastal strip with Palanga and Šventoji was transferred to the Courland Governorate. This territory was acquired from Latvia after an international arbitration in 1920. Small areas in northernmost Grodno Governorate were given to Lithuania after it "joined" the Soviet Union in 1940.
