The strategic location on the Tigris River for trade and transportation likely influenced the early settlement of Baghdad. Its proximity to important trade routes and fertile land for agriculture made it an attractive location for settlers. Additionally, the political stability and patronage of the Abbasid Caliphs played a significant role in the city's growth and development.
The golden period of Islam was most likely the rule of the early Ummayad and Abbasid Caliphs, whereupon most of the islamic middle east was united under a single ruler. Under the early Sunni Abbasid caliphs, in particular the Caliph Harun al-Rashid, science and art flourished, in a time where Islamic culture vastly surpassed western European society (which still dwelled in the dark ages). The Golden age of islam can best be seen as the time period between 750 AD- 1258 AD, brought to an end by, not so much the Crusades but more the Mongol invasion, the death of the last Caliph and the gradual political fragmentation of the Islamic world.
