Following the Russian Revolution in 1917, the British had to reevaluate its position on the Caucasus region (Georgia, Armenia and Azerbaijan). The Caucasus had been the scene of major fighting between the Ottomans and the Russian Empire during the early years of the First World War, but the events of 1917 led to the formation of independent Caucasian states, which would ultimately be incorporated into Soviet Union. Britain, between the years 1917 and 1921, had Middle Eastern interests to protect and developed policies to meet the new demands. Kaya Tunçer Çaglayan’s study is the first work to focus on the policies of Britain during this period. Çaglayan identifies two main periods, that in which military considerations prevailed, and then that in which it was active diplomatically. The Caucasus is considered as a facet of the larger regional struggles between the nascent Turkish republic, Soviet Russia and the British Empire.
