This was the age when Christianity became the official religion of the Roman Empire. In Europe missionaries were spreading Christianity to its outer regions like Britain. At the same time there were important technological developments in China, and of mathematics in India, and the beginnings of developments in the Islamic empire. An age of transition, part of the Dark Ages in Europe. At the end of this period in Europe a partial revival began under the rule of Charlemagne who supported learning through his techer Alcuin.
"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."

525 Dionysius Exiguus a Christian scholar who proposed a reform of the calendar, numbering years according to the age of Jesus in that year, described as Anno Domini (abbreviated AD) meaning "In The Year of Our Lord" followed by the number from 1 upwards. Preceding years were later referred to as BC (Before Christ) also numbered from 1 upwards. Thus there is no "year zero", only the time zero or datum point where 1 BC meets AD 1, and Jesus was somewhat paradoxicaly born on 25 December 1 BC. Later research however placed the birth of Jesus earlier, or questions his historical reality. W
