The city of Baghdad is often said to have been founded on the west bank of the Tigris on 30 July 762 by the Abbasid dynasty. Within a generation of its founding, Baghdad became a hub of learning and commerce. The House of Wisdom was an establishment dedicated to the translation of Greek, Middle Persian and Syriac works. Baghdad was likely the largest city in the world from shortly after its foundation until the 930s.
|Baghdad was designed by Naubakht, a former Persian
and Mashallah, a Jew from Khorasan, Iran.
