Does that have anything to do with Islam or more with autocracy? I'm not being snarky, I live in Saudi Arabia and certainly see the benefits of having an autocratic government for some things. I'm not sure religion plays a bigger role here in planning than it would anywhere else, though.
Good point. I think its a little bit of both. I don't think you need autocracy as much as a strong state: and Islamic states were pretty strong. But the common religion basically meant that a muslim in India could travel to Baghdad and have something in common. It meant that technological advancements in one part of the world would travel faster to the other. That skilled people could travel to different countries...and religious scholars as well. I believe this contributed a lot to the progress in Islamic society during this time.
