How large was Baghdad?

Answer 1

At its peak during the 8th to 13th centuries, particularly during the Abbasid Caliphate, Baghdad was one of the largest cities in the world, with an estimated population of over a million residents. The city spanned approximately 100 square miles, featuring a circular design centered around the Grand Mosque and the Caliph's palace. It was a major cultural, commercial, and intellectual hub, renowned for its wealth and influence. However, its size and population declined significantly after the Mongol invasion in 1258.
