How might the centralization of government have promoted commerce and technology

Centralization is a process by which planning and decision-making of an organization are concentrated in one group or location. It promoted commerce and technology because policies and regulations can be effectively implemented. Hope this answers the question. Have a nice day.

Well it depends who are you asking a muslim or a non muslim like I am a non muslim but i would say it is like a day of rebirth for them that they can adore Allah.
