‘role of Subedei, Batu, Hulegu, Khubilai and Berke; civil war and disunity by 1264.’
The Mongol Empire in the thirteenth century combined extraordinary military leadership with internal rivalries that shaped its rapid expansion and eventual fragmentation. Understanding the roles of key commanders such as Subedei and the impact of political divisions leading to disunity by 1264 is crucial for explaining both the empire’s strength and its limits.
Subedei: Master of Strategy
Early Career and Role under Genghis
Subedei (c.1175–1248) was one of Genghis Khan’s most important generals, rising from humble origins to become a leading military strategist.
He joined Genghis in his youth and became a close companion.
His brilliance lay in planning large-scale campaigns, often over thousands of miles, with coordinated multi-pronged attacks.
Subedei: A principal Mongol general and strategist under Genghis Khan and Ögedei, responsible for key victories in Asia and Europe through innovative planning and execution.
Subedei was instrumental in the conquest of the Khwarazmian Empire, devising campaigns that exploited speed, surprise, and mobility.
European Campaigns
In the 1230s, Subedei directed Mongol incursions into Eastern and Central Europe.
He masterminded the invasions of Hungary and Poland (1241), defeating armies at Liegnitz and Mohi.

The main and flanking attacks illustrate feigned retreat and converging columns characteristic of Subedei’s operational style. Use this to visualise how coordination and mobility produced decisive breakthroughs. Source
His tactics included feigned retreats, encirclement, and the use of intelligence networks to exploit enemy weaknesses.
Subedei’s strategies demonstrated the Mongols’ ability to project power far beyond the steppe, terrifying European rulers.
Batu and the Golden Horde
Rise of Batu
Batu Khan, a grandson of Genghis, commanded the western campaigns with Subedei as his chief strategist.
Together they consolidated Mongol rule over the Rus’ principalities.
Batu established the Golden Horde, a khanate that dominated the Eurasian steppe.
Batu’s leadership balanced military conquest with pragmatic governance, incorporating local princes as tributaries. However, his rivalry with other Mongol princes sowed the seeds of division.
Hulegu and Expansion into the Islamic World
Campaigns in the Middle East
Hulegu, another grandson of Genghis, led the Mongols into Persia and the Islamic world.
His most infamous campaign was the destruction of Baghdad in 1258, ending the Abbasid Caliphate.
He established the Ilkhanate in Persia, extending Mongol influence deep into the Middle East.
Hulegu’s rule was marked by both cultural flourishing and brutal conquest, but his conflict with other Mongol rulers weakened unity.
Rivalry with Berke
Hulegu’s campaigns brought him into conflict with Berke, Batu’s brother and successor in the Golden Horde. Berke had converted to Islam and was outraged by Hulegu’s sack of Baghdad.
The two khans waged open war, marking the first major intra-Mongol conflict.
This division was a turning point in the disintegration of unified Mongol authority.
Khubilai and the Question of the Khaganate
Rise of Khubilai
Khubilai, grandson of Genghis, pursued dominance in China and sought to become Great Khan.
His focus on ruling China marked a shift from traditional steppe conquest to a sedentary, imperial style of government.
He established the Yuan dynasty in 1271, aiming to legitimise Mongol rule over China.
Opposition and Civil War
Khubilai’s claims to the khaganate were disputed.
Rival branches of the family, especially those supporting Ariq Böke, opposed him.
The Toluid Civil War (1260–1264) pitted Khubilai against Ariq Böke, reflecting deep divisions among Genghis Khan’s descendants.
Civil War of 1260–1264 (Toluid Civil War): The conflict between Khubilai Khan and his brother Ariq Böke over succession to the Great Khanate, ending with Khubilai’s victory.
This war drained resources, undermined unity, and confirmed the fragmentation of the empire into semi-independent khanates.
Civil War and Disunity by 1264
Causes of Disunity
By 1264, the Mongol Empire had reached its widest territorial expanse, but political fractures undermined cohesion:
Succession disputes: Rival claimants to the title of Great Khan destabilised governance.
Religious divisions: Berke’s conversion to Islam created ideological splits with Hulegu’s Ilkhanate.
Regionalism: Rulers such as Batu, Hulegu, and Khubilai prioritised their own domains, leading to separate khanates.
Effects of Disunity
The once unified empire fragmented into four major khanates: the Golden Horde, Ilkhanate, Chagatai Khanate, and the Yuan dynasty.
The authority of the Great Khan in Karakorum diminished, as regional rulers pursued their own policies.
Although Mongol military strength remained formidable, internal conflicts prevented coordinated campaigns, limiting further expansion.
Significance of Subedei and the Division
Subedei’s career highlighted the extraordinary potential of Mongol strategy and the importance of unified command under Genghis and Ögedei. However, after his death in 1248, the empire lacked a general of comparable genius, and leadership became increasingly divided. The rivalry between Batu, Hulegu, Khubilai, and Berke demonstrated how personal ambition, religious difference, and regional priorities eroded the unity that had allowed Subedei’s campaigns to succeed. By 1264, civil war had institutionalised division, reshaping the Mongol Empire into a constellation of khanates rather than a single centralised power.
FAQ
Subedei’s victories at Liegnitz and Mohi spread fear of the Mongols across Europe. Reports of his use of speed, coordination, and psychological warfare exaggerated the Mongols as an unstoppable force.
His campaigns shaped European defensive strategies, encouraging rulers to strengthen fortifications and seek alliances, even though the Mongols withdrew soon after due to succession crises.
Subedei excelled in operational planning and large-scale coordination, often serving under others but directing strategy.
Batu focused on consolidating control in the western steppe, combining conquest with governance.
Hulegu was notable for his brutality in the Middle East and establishment of a settled administration.
Subedei was less political, while Batu and Hulegu pursued territorial authority.
Berke’s conversion created ideological tension within the empire. As ruler of the Golden Horde, he opposed Hulegu’s destruction of Baghdad in 1258, aligning himself with the Mamluks.
This marked the first time religion influenced Mongol rulers’ foreign policy, turning an internal rivalry into an ideological and military conflict that weakened unity.
The war between Khubilai and Ariq Böke (1260–1264) was not just a succession crisis but a turning point in empire structure.
It confirmed that regional power was stronger than the centre.
It showed that logistical resources could not sustain prolonged internal wars.
It set a precedent for khanates acting independently rather than as parts of a whole.
No. Subedei died in 1248, before the worst of the succession disputes and the Toluid Civil War.
However, he was aware of rising tensions, particularly after Ögedei’s death in 1241 when military campaigns stalled because generals had to return for succession councils.
His death deprived the Mongols of their greatest strategist just as political cohesion began to fracture.
