Ober Ost (situation in 1915–1917) In 1795, the historical
Duchy of Courland and Semigallia was annexed into the
Russian Empire and organized as the
Courland Governorate. In 1915, during the
First World War, almost entire territory of the Governorate, including its capital city of
Jelgava (), was occupied by German forces, that incorporated those regions into the wider militarily-administered province known as the
Ober Ost. Under the German military administration, political leaders of local
Baltic Germans began a process of forming provincial councils, and also proposing plans for future forms of governance over Courland and other Baltic regions, based on close ties with Germany. By September 1917, German imperial forces also captured
Riga, the capital city of the neighboring
Governorate of Livonia, but a major part of that governorate remained under the control of the
Russian Provisional Government. In those regions, the
Latvian Provisional National Council was created on 16 November 1917, and already on 30 November, it proclaimed
Latvia as an autonomous province, within the ethnographic boundaries of the
Latvian people. On 15 January 1918, they proclaimed Latvia as an independent republic. Thus, two political options emerged in Livonia and Courland: one advocating for independent Latvia, and the other (led by leaders of local Baltic Germans) advocating for close political ties with Germany. In February 1918, German forces captured the rest of the
Governorate of Livonia and also the
Autonomous Governorate of Estonia. By the
Treaty of Brest-Litovsk (3 March 1918),
Soviet Russia accepted the loss of all lands to the west of the agreed
demarcation line, thus effectively accepting the loss of Courland. Taking initiative, leaders of local Germans met in Jelgava on 8 March and proclaimed the re-establishment of the
Duchy of Courland, offering the ducal crown to the German emperor. == Recognition ==
