Tolui was a central figure in the early expansion of the Mongol Empire. He was the youngest son of the famous leader Genghis Khan and his wife, Börte.

While he was the youngest of four brothers, he was highly respected for his military skill. His older brothers were named Jochi, Chagatai, and Ögedei. Many people believed Tolui was actually the finest warrior among all the sons. His role in the empire was both military and political, helping to shape how the Mongols ruled vast territories.

Tolui's path to power was tied to a tradition called ultimogeniture. This is a system where the youngest son is often a leading candidate to succeed the leader. His position became even stronger after his brothers Jochi and Chagatai were removed from the line of succession. Jochi was questioned regarding his legitimacy, while Chagatai was seen as too arrogant. Although Genghis Khan eventually chose his second son, Ögedei, to be the next Great Khan, Tolui remained a vital part of the ruling family. He played a key role in maintaining the stability of the empire during times of transition.

As a general, Tolui participated in many major Mongol military campaigns. He commanded armies during the first invasion of Jin China between 1211 and 1215. During the siege of Xijing, Genghis Khan was wounded by an arrow. In that moment, Tolui was appointed to lead the army besieging the city. He also took part in the invasion of the Khwarazmian Empire.

This campaign involved moving through large areas of Central Asia to expand Mongol influence.

In 1221, Tolui was sent to manage the wealthy region of Khorasan. His mission was to pacify the area and ensure no more rebellions occurred. He led an army of approximately 7,000 men, which included Khwarazmian conscripts. This force was about one-tenth of the total Mongol invasion force. Tolui moved through several major cities, including Merv, Nishapur, and Herat. His campaign in this region was described by historians as being carried out with extreme thoroughness.

Tolui's actions in Khorasan resulted in significant loss of life and widespread destruction. In the city of Merv, the population surrendered after a seven-day assault. Although Tolui had promised to treat them fairly, he instead ordered a massacre of the people. Medieval chroniclers claimed that millions died in these battles. While modern historians believe these specific numbers are exaggerated, they agree the violence was abnormal. The scale of the damage to the population was a massive catastrophe for the region.

In the city of Nishapur, the conflict was even more intense. The inhabitants had previously killed a Mongol relative, which the Mongols viewed as a grave insult. When Tolui arrived in April 1221, the city was captured quickly. Historical records state that the city was razed and almost the entire population was killed. Even animals like cats and dogs were not spared in the destruction. This event showed the severity with which the Mongol leadership responded to perceived insults.

Tolui's legacy continued through his children and his wife, Sorghaghtani Beki. He and Sorghaghtani had several sons who became very influential. His son Möngke became the fourth Great Khan of the empire. His son Kublai became the fifth Great Khan. Another son, Hulagu, founded the Ilkhanate, a separate Mongol state. After Tolui died in 1232, Sorghaghtani Beki used her wealth and influence to help her son Möngke rise to power in 1251.

Tolui's death in late 1232 remains a subject of historical debate. The official record states he died during a shamanic ritual. The story claims he was trying to save his brother Ögedei from a curse. However, other theories suggest he may have died from alcoholism. Some even suggest he was poisoned by Ögedei. Regardless of how he died, Tolui's life was deeply connected to the rise of one of history's largest empires.
