The answer is “he states that it spread from the middle east” , because first he talks about florence, italy :)
The abbasid dynasty tried to make an empire founded on the equal
opportunity of all Muslims. The new rulers stopped the large military subjugations,
finishing the supremacy of the Arab military class. Under the early
Abbasids, the domain of the caliphs touched its utmost prosperity and control
and the Muslim civilization succeeded. Under the Abbasids, Islam turn out
to be a more varied religious because discernment against non-Arab Muslims finished.
The Abbasids also stimulated the capital from Damascus to Baghdad.
This transfer into Persian land permitted Persian administrators to hold significant
offices in the caliph's government.
