Golden Horde, Russian designation for the Ulus Juchi, the western part of the Mongol empire, which flourished from the mid-13th century to the end of the 14th century. The people of the Golden Horde were a mixture of Turks and Mongols, with the latter generally constituting the aristocracy.
The ill-defined western portion of the empire of Genghis Khan formed the territorial endowment of his eldest son, Juchi. Juchi predeceased his father in 1227, but his son Batu expanded their domain in a series of brilliant campaigns that included the sacking and burning of the city of Kyiv in 1240. At its peak the Golden Horde’s territory extended from the Carpathian Mountains in eastern Europe to the steppes of Siberia. On the south the Horde’s lands bordered on the Black Sea, the Caucasus Mountains, and the Iranian territories of the Mongol dynasty known as the Il-Khans.
Batu founded his capital, Sarai Batu, on the lower stretch of the Volga River. The capital was later moved upstream to Sarai Berke, which at its peak held perhaps 600,000 inhabitants. The Horde was gradually Turkified and Islamized, especially under their greatest khan, Öz Beg (1312–41). The Turkic tribes concentrated on animal husbandry in the steppes, while their subject peoples, East Slavs, Mordvinians, Greeks, Georgians, and Armenians, contributed tribute. The Russian princes, particularly those of Muscovy, soon obtained responsibility for collecting the local tribute. The Horde carried on an extensive trade with Mediterranean peoples, particularly their allies in Mamluk Egypt and the Genoese.
The Black Death, which struck in 1346–47, and the murder of Öz Beg’s successor marked the beginning of the Golden Horde’s decline and disintegration. The Russian princes won a signal victory over the Horde general Mamai at the Battle of Kulikovo in 1380. Mamai’s successor and rival, Tokhtamysh, sacked and burned Moscow in retaliation in 1382 and reestablished the Horde’s dominion over the Russians. Tokhtamysh had his own power broken, however, by his former ally Timur, who invaded the Horde’s territory in 1395, destroyed Sarai Berke, and deported most of the region’s skilled craftsmen to Central Asia, thus depriving the Horde of its technological edge over resurgent Muscovy.
In the 15th century the Horde disintegrated into several smaller khanates, the most important being those of Crimea, Astrakhan, and Kazan. The last surviving remnant of the Golden Horde was destroyed by the Crimean khan in 1502.
