Map 24: Disintegration of the Mongol Empire
K
ublai Khan (ruled 1260-1294) was probably the last,
true supreme khan of the Mongol domain. A suc-
cessful warrior and administrator, he led the Mongols in
the conquest of China and effectively administered the
empire's military, political and diplomatic affairs. Even
with a large pool of local and international advisers at his
disposal, however, he could not prevent the process of
disintegration of the state. With the conquest of sophisti-
cated settled areas of China, Central Asia and the Middle
East came increased involvement in everyday adminis-
tration and the running of the numerous provinces of the
empire. The centralized nature of the state led to lengthy
delays in major decision making because transportation
and communication technologies were still quite primi-
tive and undeveloped. For example, it could take from
six to fifteen weeks for a messenger to carry a letter from
Samarqand to Karakorum. Hence many governors and
local khans exercised increasing autonomy over various
issues, independent of the center.
At the same time, another important factor con-
tributed to the disintegration processes in the Empire—
proselytism. The Mongols were noted for their religious
tolerance and interest in spirituality. In the case of Central
Asia, it is probable that Berke (ruled 1257-1267), grand-
son of Genghis Khan, had already converted to Islam, and
likewise Baraq (ruled 1266-1271), Ghazan Khan (ruled
1295-1305), Uzbek (ruled 1313-1341) and others adopted
the Muslim faith. Though Islamization took another 100
to 150 years, the process had a huge impact on relations
between the center and periphery, as it created a deep
divide between the shamanistic and later Buddhist
Mongols and their Muslim kinfolk. Through conversion,
the Mongols were transformed from political and cultural
outsiders to political and cultural insiders. Increasingly
zealous Muslim khans of the Chagatai khanate, the
Golden Horde and И Khanate began distancing them-
selves from traditional shamanistic practices, thus foster-
ing the political isolation of the center in Karakorum.
In addition, several other factors contributed to the
decline of the Mongols' military power, with three
probably playing key roles in the process: climate
change; disease, especially in the form of outbreaks of a
pandemic; and social-demographic factors (a decreasing
birth rate and high levels of alcoholism among the
Mongol elite). Recent studies indicate that between
the late thirteenth and mid-fourteenth centuries, the
Eurasian continent experienced a "Little Ice Age."
Animal herders were particularly vulnerable to the
extreme winters as their animals relied on natural pas-
ture. In such winters the Mongols' horses—a major
source of food, their chief form of transportation and the
basis for their cavalry—would die en masse, leading to
malnutrition, starvation, even famine among the general
population. Against this background, the Black Death,
the pandemic that killed nearly half of Europe's popula-
tion in the first half of the fifteenth century, could have
similarly affected the Eurasian steppe. Some scholars
believe that the Black Death had in fact originated in
China and Central Asia and was brought to the Middle
East and Europe by the Mongols and their merchants.
Many families in this time were experiencing a
chronic social malaise, as never-ending military cam-
paigns took young people away from their families for
years, thus contributing to a falling birthrate and erosion
of family cohesion. It is not surprising, therefore, that in
such a time of social degradation and death many mem-
bers of the Mongol aristocracy turned to alcohol, liter-
ally drinking themselves to death. This might well
explain why many Mongol princes died relatively
young.
In the late thirteenth and early fourteenth centuries
the Mongol rulers were also engaged in a deadly cycle of
internecine wars. Even Kublai Khan struggled for recog-
nition among some Mongol tribes; several members of
the Genghis family did not acknowledge his authority,
including his own younger brother Arikbukha (?—1266).
Another significant rival was Kaidu Khan (1230-1301),
great-grandson of Genghis Khan. Kaidu Khan, together
with Duwa Khan (ruled 1282-1307), a ruler of the Ulus
of Chagatai, spent almost his entire reign fighting other
competitor-princes for superiority in the empire. In
1285, Duwa Khan's troops even took on and defeated
the army loyal to Kublai Khan, and began a campaign in
eastern Turkistan for three years. In the 1290s Duwa
Khan constantly campaigned against his neighbors and
rivals in Khorasan, Maveranahr and eastern Turkistan.
He also participated in internecine wars among Genghis
Khan's descendants from 1300 to 1304 and 1305 to 1306
in Mongolia. He effectively exhausted the Mongol
armies in these numerous campaigns, which he pursued
almost until his death in 1307 (Biran 1997).
In the early fourteenth century, the conflicts among
members of the royal family further sped up the process
of disintegration. Kebek Khan (ruled ca. 1318-1326)
moved his administrative center from Jetysuu to
Maveranahr. After his death the khanate slid into two
decades of political chaos and was ruled by various
khans whose reigns generally lasted between two and
five years. During this era many princes neglected their
administrative, diplomatic and political duties and
largely returned to a traditional nomadic life, indulging
themselves in hunting, small military campaigns and
family wars. The political chaos undermined economic
development and further weakened the numerous
members of the Genghis clan in Central Asia. In this
environment, a new regional leader emerged.
