The
Russian Empire had conquered
Central Asia in the 19th century, by annexing the formerly independent Khanates of
Kokand and
Khiva and the
Emirate of Bukhara. 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". The NTD is commonly portrayed as being nothing more than a cynical exercise in
divide and rule, a deliberately Machiavellian attempt by Stalin to maintain Soviet hegemony over the region by artificially dividing its inhabitants into separate nations and with borders deliberately drawn so as to leave minorities within each state. Though indeed the Soviets were concerned at the possible threat of
pan-Turkic nationalism, 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. The Soviets aimed to create ethnically homogeneous republics, however many areas were ethnically-mixed (e.g. the
Ferghana Valley) and it often proved difficult to assign a ‘correct’ ethnic label to some peoples (e.g. the mixed Tajik-Uzbek
Sart, or the various Turkmen/Uzbek tribes along the Amu Darya). Local national elites strongly argued (and in many cases overstated) their case and the Soviets were often forced to adjudicate between them, further hindered by a lack of expert knowledge and the paucity of accurate or up-to-date ethnographic data on the region. 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. 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. Additionally the Soviets never intended for these borders to become international frontiers as they are today. in 1922 before national delimitation NTD of the area along ethnic lines had been proposed as early as 1920. At this time Central Asia consisted of two Autonomous Soviet Socialist Republics (ASSRs) within the
Russian SFSR: the
Turkestan ASSR, created in April 1918 and covering large parts of what are now southern Kazakhstan, Uzbekistan and Tajikistan, as well as Turkmenistan, and the
Kirghiz Autonomous Soviet Socialist Republic (Kirghiz ASSR, Kirgizistan ASSR on the map), which was created on 26 August 1920 in the territory roughly coinciding with the northern part of today's Kazakhstan (at this time Kazakhs were referred to as ‘Kyrgyz’ and what are now the Kyrgyz were deemed a sub-group of the Kazakhs and referred to as ‘Kara-Kyrgyz’ i.e. mountain-dwelling ‘black-Kyrgyz’). There were also the two separate successor ‘republics’ of the
Emirate of Bukhara and the
Khanate of Khiva, which were transformed into the
Bukhara and
Khorezm People's Soviet Republics following the takeover by the
Red Army in 1920. On 25 February 1924 the
Politburo and
Central Committee of the Soviet Union announced that it would proceed with NTD in Central Asia. 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. There were initial plans to possibly keep the Khorezm and Bukhara PSRs, however it was eventually decided to partition them in April 1924, over the often vocal opposition of their Communist Parties (the Khorezm Communists in particular were reluctant to destroy their PSR and had to be strong-armed into voting for their own dissolution in July of that year). The creation of the Kazakh-Uzbek border proved particularly difficult in the
Syr-Darya Oblast, a densely settled area where populations were mixed. Both Uzbeks and Kazakhs claimed the cities of
Turkistan,
Chinaz and
Shymkent;
Tashkent – a predominantly Uzbek city surrounded by Kazakh areas – proved particularly troublesome, with the Central Asian Bureau eventually being forced to decide on the matter, awarding the city to Uzbekistan. Kazakhstan however gained the large city of Shymkent. A further complication were the
Karakalpaks; the Soviets were unsure if they were Uzbeks, Kazakhs or a separate nationality altogether. Given the at-best weak sense of Karakalpak nationality, and their perceived closer links to the Kazakhs, they were given their own
Karakalpak Autonomous Oblast within the
Kazakh ASSR. This oblast was larger than the modern autonomous
Republic of Karakalpakstan and extended considerably further eastwards, thereby cutting the Uzbek SSR in two, with a small exclave around
Khiva. Poor economic performance in the oblast convinced Soviet leaders that Karakalpakstan should be included directly the
Russian SSR, a move formalised in 1930; it was upgraded to
ASSR status in 1932. In 1936 the area was transferred to the Uzbek SSR. Many older maps show a slightly different boundary in the Kara-Kum desert, with a large triangular protrusion of Uzbek territory into what is now Kazakhstan's
Kyzylorda Region (
see maps right). According to the Resolution of the Presidium of the Supreme Soviet of the USSR of February 13, 1956,
Mirzachoʻl desert and
Boʻstonliq District was separated from
Kazakh SSR (
South Kazakhstan Region) and added to
Uzbek SSR along its northeastern frontiers. In 1963, in accordance with the decision of the Presidium of the Supreme Soviet of the USSR, an additional 36,600 square kilometers of territory was transferred from
South Kazakhstan and
Kyzylorda regions of
Kazakh SSR. The boundary became an international frontier in 1991 following the
dissolution of the Soviet Union and the independence of its constituent republics. There were various tensions around the border – especially in the Tashkent area - in the late 1990s-early 2000s, with Kazakhstan accusing Uzbekistan of unilaterally demarcating and militarising the border; eventually in 2001 the two governments agreed to begin a full delimitation of the border. The process of delimiting the Kazakhstan-Uzbekistan border took place from 2000 to 2002 and presented challenges due to 200 km of densely populated border areas, such as the
Saryagash and
Maktaaral Districts in South Kazakhstan Region and the Tashkent and Jizzakh regions in Uzbekistan. Specific difficulties arose in defining the borderline, as previous agreements had placed the boundary along the
Keles River. Seasonal flooding altered the river’s path, leading both countries to agree on marking the border along its current course. Other complexities included sections around the
Shardara Reservoir, where lands had been temporarily ceded to Uzbekistan. One of the most challenging issues was the division of the villages of Bagys and Turkestanets, which sat directly on the border. A review of historical maps revealed inconsistencies: Bagys, which was not listed on maps from the 1940s and 1960s despite being inhabited, lay across the boundary. Residents of Bagys and Turkestanets expressed a preference to remain in Kazakhstan. While Uzbekistan made no claims to Bagys, it noted that Turkestanets had been under the jurisdiction of its
Ministry of Defense since the collapse of the USSR. Ultimately, Bagys was integrated into Kazakhstan, and residents of Turkestanets who wished to stay in Kazakhstan relocated. An exchange of 517 hectares of mountainous pastures in the Bagys area for semi-desert lands near the villages of Nysan-1, Nysan-2, and Baimurat in the Kyzylorda Region helped finalize the agreement. A similar approach resolved other disputes, including those near the Arnasay Dam. Full demarcation is currently ongoing. On March 28, 2023, both countries finally ratified the border demarcation treaties. ==Border crossings==
