On the Grasslands: A Name Begins
In the vast grasslands of Mongolia, on 24 March 1282, a son was born who would later change the face of Western Asia. His name in Mongolian, Öljaitü, means "blessed" — a fitting title for a man who ultimately brought blessings to Islamic civilization. However, his destiny was not just to be a ruler; Öljaitü was one of the most controversial figures in Ilkhanate history, because he embraced Islam and changed his name to Mohammad-e Khodabandeh — "servant of God" in Persian.
Öljaitü was the son of Arghun Khan, the fourth ruler of the Ilkhanate, and the brother of Mahmud Ghazan, the famous fifth ruler. He was also the grandson of Hulegu Khan, the feared founder of the Ilkhanate, and the grandson of Genghis Khan. This royal blood flowed in his veins, but more than that, he inherited a vision to unite the fragmented lands due to war.
From Buddhism to Islam: The Spiritual Journey of a Khan
Before embracing Islam, Öljaitü was raised in the Buddhist faith, like most early Mongol nobles. However, as recorded by historian Rashid al-Din Hamadani in his work
Jami' al-tawarikh, Öljaitü was exposed to various religions in the Ilkhanate court — including Nestorian Christianity, Buddhism, and Islam. His change of heart happened gradually.
In 1304, after Ghazan's death, Öljaitü ascended the throne as the eighth Khan. Initially, he remained with the Buddhist faith, even reportedly considering converting to Christianity. However, the influence of his wife, a daughter from a Mongol tribe who had embraced Islam, along with the arguments of scholars such as Sayyid ibn Tawus, eventually convinced him. In 1310, he formally recited the shahada and took the name Mohammad. This event was not merely personal; it changed the state's policy. Islam became the official religion of the Ilkhanate, and all Buddhist temples and churches were closed or converted into mosques.
Soltaniyeh: A Dream City on Earth
One of Öljaitü's greatest legacies is the construction of the Soltaniyeh Mausoleum, located in the city of Soltaniyeh, now in the Zanjan region of Iran. This dome was the largest in the world at the time — 49 meters high and 25 meters in diameter, entirely made of bricks. It was completed in 1312, only four years after Öljaitü embraced Islam.
Why did Öljaitü build this tomb? According to some sources, he initially planned to move the remains of Imam Ali and Imam Husain from Najaf and Karbala to Soltaniyeh as a sign of respect and unification of Shia under his rule. However, this plan was strongly opposed by Sunni scholars, and eventually, Öljaitü decided to make it his own resting place.
The architecture of Soltaniyeh is a unique blend of Mongol, Persian, and Islamic styles. Its towering dome is adorned with blue and green tiles, while inside it contains calligraphy of Quranic verses in Kufic and Thuluth scripts. This structure is not only a symbol of the Ilkhanate's power but also a symbol of harmony between the nomadic Mongol tradition and the settled Islamic civilization.
Just and Glorious Rule
In addition to architectural development, Öljaitü was also known as a just ruler and a patron of knowledge. He maintained Ghazan's tradition by appointing Rashid al-Din as chief minister, who produced the monumental historical work
Jami' al-tawarikh. Under Öljaitü's reign, scholars from various backgrounds — Persian, Arab, Indian, and Chinese — gathered in Tabriz and Soltaniyeh to translate scientific, medical, and astronomical works.
The economy of the Ilkhanate also flourished under his rule. He introduced a stable currency system, improved agricultural irrigation, and built roads connecting Persia to China via the Silk Road. Soltaniyeh itself became a major stop for merchants from Venice to Cathay (China), making it an international center of trade and diplomacy.
Challenges and Change: From Shia to Sunni
Although Öljaitü embraced Islam, his religious views were not fixed. Initially, he leaned towards the Shia Imamiyah school, and it was said that he changed the Friday sermons in mosques to mention the names of the twelve imams. This action caused tensions with the majority Sunni population in Persia. However, in the final years of his rule, he returned to the Sunni school, possibly under the advice of his wife or political pressure.
This change shows that Öljaitü was not a blind fanatic, but a pragmatic leader trying to balance religious idealism with political reality. He died on 16 December 1316 in Tabriz from an unknown illness and was buried in the Soltaniyeh Mausoleum he built himself.
A Legacy That Lives On
Today, the Soltaniyeh Mausoleum is recognized as a UNESCO World Heritage Site since 2005. It is not only impressive in terms of architecture but also a symbol of the meeting between the Mongol and Islamic worlds. Its majestic dome has inspired Mughal architects in India, including the Taj Mahal.
Öljaitü may not be as well-known as Ghazan or Hulegu, but his contributions to Islamic civilization cannot be denied. He is proof that a Mongol Khan born in the Buddhist faith could become a devout servant of God, and that a brick dome could become a bridge between heaven and earth.
In every brick of Soltaniyeh, there is a story about a man who sought the meaning of life amidst power and finally left behind a monument of glory that will be remembered forever.
