Walled imperial capital founded on the steppe with a palace compound, segregated craft quarters and multi-faith institutions
A planned sedentary capital imposed on a nomadic empire, exceptional as a cosmopolitan foundation of the Mongol world
In 1235 Ögedei Khan, successor to Genghis Khan, ordered the construction of a permanent walled capital at Karakorum in the Orkhon valley of central Mongolia, drawing skilled artisans from Persia to China. Within a few years a roughly rectangular city of rammed earth and unfired brick had risen on the steppe, enclosing a separately walled palace compound, a treasury and arsenal, and residential quarters for foreign craftsmen. Contemporary accounts, notably that of the Franciscan William of Rubruck who visited in the 1250s, describe distinct ethnic and trade quarters — a Muslim merchants' district and a Chinese craftsmen's district — alongside Buddhist temples, mosques and a Christian church, making Karakorum a strikingly multi-religious imperial foundation.
Karakorum is the great anomaly of Mongol urbanism: a deliberately planned sedentary capital created by and for a nomadic empire that otherwise built few cities for itself. As the administrative and ceremonial heart of the Mongol world from 1235 until the capital moved to Khanbaliq under Kublai, it concentrated imperial power, long-distance trade and a cosmopolitan population, embodying the steppe empire's brief experiment with monumental fixed urban order.
Built up from a tent-town into a walled imperial capital with a columned palace, two fixed quarters and craft workshops plus multi-faith institutions; capital function moved to Khanbaliq/Dadu under Kublai in the 1260s, and the city was razed by Ming troops in 1380, after which it was abandoned and its stone reused to build Erdene Zuu monastery c. 1585.
Contemporaries judged it modest for an imperial capital - William of Rubruck likened the whole city to a single suburb (the village of Saint-Denis), reflecting its dependence on a non-urban steppe society and on imported labour and supplies.
