Explain the effects of Islamic expansion on medieval world culture

What will be an ideal response?

Islam unified the tribal population of Arabia in a common religious and ethnic bond that propelled Muslims out of their desert confines into East Asia, Africa, and the West. This expansion played a key role in defining the geographic borders of Western Europe. The control of the Mediterranean by Muslim forces snuffed out the waning Western sea trade, isolating the Christian West. As Islam expanded, it absorbed many different styles from the arts of non-Arab peoples, eventually contributing to a new, global culture.
Islam was enthusiastically receptive to the intellectual achievements of other cultures and aggressive in its will to understand the workings of the natural world. Between the ninth and twelfth centuries, Muslims absorbed and preserved much of the medical, botanical, and astrological lore of the Hellenized Mediterranean. This fund of scientific and technological knowledge, along with Arabic translations of Aristotle's works in logic and natural philosophy, and Muslim commentaries on Aristotle, filtered into the urban centers of Europe. There, in the twelfth century, they stimulated a rebirth of learning and contributed to the rise of Western universities and the Renaissance. Islamic scholars also made original contributions in mathematics, medicine, optics, chemistry, geography, philosophy, and astronomy. In the field of medicine, Islamic physicians wrote treatises on smallpox, measles, and diseases transmitted by animals (such as rabies), on the cauterization of wounds, and on the preparation of medicinal drugs. Further, at a time when most Europeans knew little of the earth's physical size or shape, geographers in Baghdad estimated with some accuracy the earth's circumference, as well as its shape and curvature. Muslim astronomers made advances in spherical geometry and trigonometry that aided religious observance, which required an accurate lunar calendar and the means of determining the direction of Mecca from any given location.
