Explain the actions that the Mongols did in Iraq?

Explanation:

Mongols arrived in 1258. Their army, estimated at over 150,000 soldiers, stood before the city that was just a shadow of the great capital of the Muslim world of the 800s. The siege began in mid-January and only lasted two weeks. On February 13th, 1258, the Mongols entered the city of the caliphs.

A full week of pillage and destruction commenced. The Mongols showed no discretion, destroying mosques, hospitals, libraries, and palaces. The books from Baghdad’s libraries were thrown into the Tigris River in such quantities that the river ran black with the ink from the books. The world will never truly know the extent of what knowledge was lost forever when those books were thrown into the river or burned.

More important than the books, however, was the loss of life. It is estimated that between 200,000 and 1,000,000 people were butchered in that one week of destruction. Baghdad was left completely depopulated and uninhabitable. It would take centuries for Baghdad to regain any sort of prominence as an important city.
