He is a Mongolian ruler, son of Emperor Tolui Genghis Khan, brother of the two emperors Kublai Khan and Manko Khan and Emperor Eric Bock, born in 1217 AD, Hulagu was fond of Persian civilization, and after he became a khan of Persia after establishing the reign of the khans there, he included in his council many scholars, philosophers and sages from Throughout Persia, which follows the Islamic religion, Hulagu was associated with Khan's Christianity, in addition to many wives.

Hulagu occupied many countries to the west of Asia, and killed millions of people in those countries. Monaco Khan assigned his brother Hulagu to lead the great Mongolian army to invade and destroy the remaining Islamic states in the southwestern part of Asia in 1255 AD, and he ordered him to treat the surrendered with mercy, and to eliminate the resistance completely.

But Hulagu carried out the last part of the orders with the utmost brutality and cruelty, so he wanted to subjugate the lords who lived in the south of Iran, and he sought to eliminate the Assassin sect and tried to destroy or subjugate the Abbasid state. Hulagu came out at the head of an army considered one of the greatest Mongol armies ever formed. .
And he began his first military operations by defeating the Lord, and after his reputation spread throughout the country, the Assassins were terrified, so they immediately surrendered and surrendered their fortified castle without a battle.

Then Hulagu's army set out for Baghdad, and before reaching it he sent to the Abbasid caliph there, asking him to surrender, but the caliph refused to surrender and sent Hulaku to warn him of Allah's punishment and punishment if he tried to attack the Caliph of Islam. He divided his army into two parts to besiege the city from the western and eastern sides, but the Caliph's army succeeded in repelling some of his attacking forces from the western side, but in the end he was defeated and the city surrendered to Hulaku and his army.

When Hulagu reached the age of thirty-six, he went out at the head of a massive army after his brother Manko Khan entrusted him to enter the country on the banks of the River Gihon, after which the Mughal state extended until reaching Egypt, and he advised him before moving to implement the laws of his great-grandfather (Genghis Khan) and adhere to customs and traditions And whoever submits to his authority must treat him with perfume, and work to exterminate those who resist him even if he is the Abbasid Caliph himself.

Hulagu achieved his first victory by seizing the fortresses of the Ismaili sect after many battles, and then went on his way towards achieving his final goal, by completely seizing the city of Baghdad and wiping out the Abbasid caliphate in it. He obeyed, but the caliph refused to comply with his orders despite the weakness of his forces.

Hulagu besieged the city and entered it in 1258 AD, and Baghdad fell into the hands of Hulagu and his forces, where he destroyed it and flooded its library in the Tigris, which was said to have turned black as a result of ink books that he drowned in it, and killed its people and plundered the city and burned it and captured the caliph and wrapped it with carpets, and after they spread a beating on it, they trampled on it. With their horses until he died, and as a result of the stench of death that spread in the city after this destruction, Hulagu was forced to move his camp away from it, and after that the city remained for a number of years empty of residents.

Hulagu set out after Baghdad intending to seize the Levant and managed to seize Mayfariqin in Aleppo, and then continued on his way towards Mardin, and during their siege of cities, the Mongolian army would invade and bring down other cities, and then advance to Aleppo, which besieged it and set up catapults around it and rained it with missiles until it surrendered After that, the Mongolian army, led by Hulagu, moved towards Damascus, and when news of their approaching King Al-Nasir Yusuf Al-Ayyubi arrived, the latter fled with his forces, leaving Damascus for its fate, but the people surrendered and surrendered the city to Hulaku without a fight.

Hulagu sent a threatening message to the Mamluks in Egypt calling them to surrender before his move from the Levant, but Sultan Qutuz did not pay attention to these threats, and went out to sermon in his army crying to stir their feelings, and he did not wait for the advance of the Mongols. King Qutuz came out at the head of his army to meet the Mongols, and his army joined forces from The Arabs, the Levant, the Turkmen and others were to fight the Mongol army, and the two armies met in the Ain Jalut area in Palestine, and fought them from the early hours of dawn until midnight.

The army of Qutuz defeated the Mongol army in that incident and wiped out the Tatar army from the end, and the skill and cunning of Al Zahir Baybars had the greatest credit for achieving this great victory, which had a great impact on the history of the region and the Arab world, after which the Mongol army was expelled from Damascus and Baghdad, which came under the rule of The Mamluks, and thanks to this great victory, Europe was saved from a great evil in the event that the Mongol army continued to march and achieve its victories, and the leader of the Golden Horde Baraka Khan, cousin of Hulagu, made an alliance with Zahir Baybars to eliminate Hulagu after he was besieged on both sides.

What happened to Hulagu after the defeat, except that he tried to avenge the defeat of his army in the battle of Ain Jalut, so he sent a strong army towards Aleppo, which he had brought down and plundered, but he was defeated near Homs and returned to beyond the Euphrates.
Then he tried to create an alliance with Europe against the Arabs and Muslims, and he sent a letter to King Louis declaring his intention to invade the city of Jerusalem for the sake of the Pope, and Louis demanded an attack on Egypt mediated by his fleet through the Mediterranean.

Hulagu died in the year one thousand two hundred and sixty-five, after doctors had failed to treat him. At the age of forty-eight, Hulagu was buried on the island of Kabudi, located in Lake Urmia, and his son succeeded him.
