In Muharram ah 617/March 1220 ce Chinggis Khan led his armies to Bukhara as part of a larger campaign against the Khwārazmshāh Empire (616–621/1220–1225). The city quickly surrendered and was rapidly integrated into the growing Mongol Empire. In the subsequent decades, Bukhara enjoyed a speedy recovery under the stewardship of a series of Mongol officials, who patronized religious institutions, repaired the damage caused by the invasion, and mitigated some of the excesses of the Mongol armies stationed in Transoxania. Yet this revival was stunted in the second half of the 13th century when the Mongol Empire was divided by war. During this period different factions contested control of Transoxania, and Bukhara became the target of periodic raids and attacks. A full rehabilitation of the city had to wait until after 716/1317–1318, when alliances between the Mongol military elites and the popular religious leaders of Bukhara facilitated a new period of stability that would last until the fall of the last effective khan, Qazān Sultan, in 746/1346. Bukhara’s status as an intellectual, economic, and political capital of Transoxania was diminished during the period of Mongol rule. Samarqand was designated as the administrative capital of Transoxania for much of this period, and the presence of Mongol forces in Nakhshab saw Bukhara subordinated to the itinerate court of the Chaghadaid-Mongol princes. Nevertheless, the city continued to be seen as an important center of religious scholarship, and its prestige was boosted by the fact that it served as the base for two of the leading Sufi movements of its time, the Kubrawiyya and the Naqshbandiyya.
By the late 19th century, when much of Islamic Central Asia was conquered by the Russian Empire, the region was home to tens of thousands of slaves. Most of these slaves were Shiʿa Muslims from northern Iran, though the slave trade also ensnared many Russians, Armenians, Kalmyks, and others. Slave labor was especially commonplace in the Sunni Muslim domains of Khwarazm and Bukhara, where enslaved people constituted a substantial proportion of all agricultural workers, domestic servants, and soldiers. Slaves also labored in many other roles, and an individual slave could be tasked with a variety of jobs. Slaves served, for example, as concubines, craftsmen, miners, herdsmen, entertainers, blacksmiths, calligraphers, and even, in rare instances, as government officials. Before the 16th century, the majority of the slaves in Central Asia—defined here as the region extending from the eastern shores of the Caspian Sea through Xinjiang, China, and from southern Siberia to northern Iran—seem to have been trafficked to the region from India. This changed in the 16th and 17th centuries, as a significant number of Iranian war-captives were brought north and enslaved during the course of numerous armed conflicts between the Central Asian Uzbeks and Iranian Safavids. Many of these slaves evidently labored on the region’s rapidly expanding agricultural estates. In the 18th and 19th centuries, frequent Turkmen raids into northern Iran resulted in tens of thousands of Iranian Shiʿas being captured and funneled into a booming slave trade in Khwarazm and Bukhara. Further north, a much smaller number of Russians were seized and sold into slavery by Kazakh nomads along the steppe frontier. The region’s slave trade declined in the late 19th century and seems to have remained dormant throughout the Soviet period. The post-Soviet period has witnessed a resurgence of human trafficking throughout Central Asia. In recent decades, local governments and international organizations have labored with mixed success to combat a new kind of slave trade, as Central Asian victims are trafficked by criminal cartels to neighboring countries, or to other regions of the world, for the purposes of forced labor or sexual exploitation.
In the 19th century, the Emirate of Bukhara was one of three independent Uzbek principalities known as khanates. Ruled by the Manghit amīrs, Bukhara was the biggest and most important of the southern Central Asian polities and one of the major power centers in the wider region. To the readers of 19th-century European travelogues, Bukhara was known for the despotism of its rulers notorious for their cruelty and strange tastes. From a geopolitical point of view, the Bukharan Emirate was part of an anarchic transition space between Central and South Asia made up of half a dozen petty principalities without centralized power structures. While the bulk of the 19th- and 20th-century secondary sources stress the despotism of its amīrs and its isolation in view of the declining caravan trade on the Central Asian caravan routes, Bukhara and other urban centers such as Samarqand and Qarshi were embedded in transregional religious and trading networks. As a crossroads of commerce and an important religious center, Bukhara in particular and other Transoxanian towns as well attracted flows of goods and people from all directions and was well connected to other places and areas such as Siberia, China, India, and Persia. In the second half of the 19th century, the Emirate of Bukhara and its neighbors north of the Āmū Daryā River came into the focus of Russia. After a series of military defeats in 1868, Bukhara was turned into a Russian protectorate, which finally became a People’s Republic after the Bolshevik conquest in 1920. This political entity was absorbed into the emerging Soviet Union in 1924.
