This was the age when Islam, from the death of Mohammed, came to dominance and served as a means of preserving the classical learning, and advancing it in various ways. In Europe missionaries were spreading Christianity to its outer regions like Britain. Christian rulers like Charlemagne supported learning. At the same time there were important technological developments in China. An age of transition, part of the Dark Ages.
"The concept embodied in the term "Dark Ages", however, has some validity. The period from the fifth to the eighth century witnessed a marked decline in intellectual activity, and a falling off of standards in sanitation, water supply, communications and domestic comfort. The obscurity of the period is a serious drawback for historians, since the lack of written records means that for most subjects the only evidence comes from scanty archaeological findings. In the Byzantine and Iranian Empires, in this period, civilisation remained at a high level, but written evidence from these two cultures is very sparse."
