Tolui was the youngest son of Genghis Khan. 
Tolui led many armies for his father. He fought in wars in China and in the Khwarazmian Empire. In the year 1221, he led a campaign in a place called Khorasan. This part of the world was very wealthy. During these wars, many people were treated very unfairly. Many people died in the cities Tolui attacked. While old stories say the numbers were huge, modern historians think they might be smaller. Still, the wars caused a lot of harm to the people living there.
After Genghis Khan died in 1227, Tolui helped run the empire. He was the regent, which means he looked after the land for a short time. He served until his brother Ögedei became the leader in 1229. 
Tolui was a major figure in the early Mongol Empire. He was the youngest son of the great leader Genghis Khan and his wife, Börte. 
Tolui's life involved many difficult and serious tasks. He led soldiers during the first invasion of Jin China between 1211 and 1215. Later, he fought in the Khwarazmian Empire to expand Mongol control. In 1221, he was sent to a wealthy region called Khorasan. His job was to make sure no one fought against the Mongols there. He led an army of about 7,000 men to finish this hard job. He moved through cities like Merv and Nishapur to take control.
During his time in Khorasan, Tolui's actions caused great sadness. He attacked several large cities to make sure the region was under Mongol rule. In the city of Merv, he did not keep a promise to be fair to the people. In Nishapur, the fighting was very violent because the city had insulted the Mongols before. 
Tolui's family was also very important to history. He married a woman named Sorghaghtani Beki. They had several sons, including Möngke, Kublai, and Hulagu. These sons grew up to be very powerful leaders themselves. Möngke and Kublai became khans, which were the great rulers of the empire. Hulagu even started his own land called the Ilkhanate. Because of his sons, Tolui's family stayed in power for a long time.
After Genghis Khan died in 1227, Tolui held a special role. He served as the regent, which means he looked after the empire for a while. He did this until his brother Ögedei became the new leader in 1229. Tolui died in late 1232, but the reasons are not clear. Some old records say he died during a ritual to save his brother. Other ideas say he died from sickness or something else. His wife, Sorghaghtani Beki, later helped their son Möngke take power in 1251.
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. 
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. 
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.
