The Ismailis are one of the largest Muslim minority populations of Central Asia, and they make up the second largest Shiʿi Muslim community globally. First emerging in the second half of the 8th century, the Ismaili missionary movement spread into many areas of the Islamic world in the 10th century, under the leadership of the Ismaili Fatimids caliphs in Egypt. The movement achieved astounding success in Central Asia in the 10th century, when many of the political and cultural elites of the region were converted. However, a series of repressions over the following century led to its almost complete disappearance from the metropolitan centers of Central Asia. The movement later re-emerged in the mountainous Badakhshan region of Central Asia (which encompasses the territories of present-day eastern Tajikistan and northeastern Afghanistan), where it was introduced by the renowned 11th-century Persian poet, philosopher, and Ismaili missionary Nasir-i Khusraw. Over the following centuries the Ismaili movement expanded among the populations of Badakhshan, reaching a population of over 200,000 in the 21st century. In the 19th and 20th centuries, the Ismailis suffered a series of severe repressions, first under local Sunni Muslim rulers and later under the antireligious policies of the Soviet Union. However, in the decades since the end of the Soviet period, the Ismailis of the region have become increasingly connected with the global Ismaili community and its leadership. While many aspects of the history of Ismailism in the Badakhshan region remain obscure and unexplored, the discoveries of significant corpuses of manuscripts in private collections since the 1990s in the Badakhshan region have opened up wide possibilities for future research.
The Khanate of Khiva, one of the Uzbek khanates of Central Asia, refers to a political entity in the region of Khorezm from the early 16th century until 1920. The term itself, which was not used by locals who instead used the name vilayet Khwārazm (“country of Khwārazm”), dates from 18th-century Russian usage. Khorezm is an ancient center of sedentary civilization with a distinct culture and history that came under Uzbek rule as the latter migrated southward from their pasturelands on the steppe beginning in the early 16th century. In contrast to the related dynasties in Transoxiana, the Khanate of Khiva retained a greater degree of pastoralism, though the state was still fundamentally built on sedentary agriculture. Though no doubt affected by historical variations in the volume and routes of the overland caravan trade, Khiva remained a key center for transregional trade throughout its history, especially with the growing Russia Empire to the north. Political structures in Khiva remained weak and decentralized until the 19th century, when the Qongrat dynasty succeeded in transforming the khanate into the most centralized state in the region. Among the legacies of the khanate is its promotion of a distinctive Turkic literary culture, which interacted fruitfully with the dominant Persian culture of neighboring regions. As with other states in Central Asia, by the second half of the 19th century Khiva became a target of the expanding Russian Empire, which conquered Khorezm in 1873. While the tsarist state initially preserved a portion of the khanate under Qongrat rule as a protectorate, after the Bolshevik Revolution this state was soon dissolved and absorbed into the Soviet Union.
