Answer:
The best answer to the question: What did the introduction of silk into the Mediterranean do for the Abbasid Empire, would be: It helped secure economic stability for the Abbasid Empire.
Step-by-step explanation:
The Abbasid dynasty took over control of the Persian Empire in 750 C.E, after they had overthrown the old Umayyad dynasty. They became well known not just for their protection of non-Arab Muslim people, but also for extending the power of the Persian Empire and establishing the capital of it in Baghdad in 762 C.E. The Abbasid became also very well known for their strength in trade, and particularly for their trade in goods from the far East, such as spices, diamonds, ivory and also silk. With the establishment of the silk trade with the Mediterranean nations, the Abbasid were able not only to secure economic stability, but expand and strengthen their empire.
