Tajikistan–Uzbekistan border

The border then follows this range westwards, before turning south in the vicinity of the Uzbek town of Olmaliq at the Syr Darya river.

The next section of the boundary is extremely convoluted, with a long protrusion of Tajik territory (Zafarobod District) and a series of irregular lines; eventually the border proceeds roughly southwards before turning sharply west upon reaching the Turkestan Range.

After the Communists took power in 1917 and created the Soviet Union it was decided to divide Central Asia into ethnically-based republics in a process known as National Territorial Delimitation (or NTD).

This was in line with Communist theory that nationalism was a necessary step on the path towards an eventually communist society, and Joseph Stalin's definition of a nation as being “a historically constituted, stable community of people, formed on the basis of a common language, territory, economic life, and psychological make-up manifested in a common culture”.

[2] Though indeed the Soviets were concerned at the possible threat of pan-Turkic nationalism,[3] as expressed for example with the Basmachi movement of the 1920s, closer analysis informed by the primary sources paints a much more nuanced picture than is commonly presented.

[7][9] Furthermore, NTD also aimed to create ‘viable’ entities, with economic, geographical, agricultural and infrastructural matters also to be taken into account and frequently trumping those of ethnicity.

[10][11] The attempt to balance these contradictory aims within an overall nationalist framework proved exceedingly difficult and often impossible, resulting in the drawing of often tortuously convoluted borders, multiple enclaves and the unavoidable creation of large minorities who ended up living in the ‘wrong’ republic.

[15][16] The process was to be overseen by a Special Committee of the Central Asian Bureau, with three sub-committees for each of what were deemed to be the main nationalities of the region (Kazakhs, Turkmen and Uzbeks), with work then exceedingly rapidly.
