The Dark Ages

What actually happened

"Dark Ages" was a piece of branding. Petrarch coined it in the 1330s to flatter his own era by contrast, and Enlightenment writers extended it as a swipe at the medieval church. It was never a neutral description, and by the late twentieth century medievalists had largely abandoned it. Where it survives in scholarship at all, it refers narrowly to the sparse documentary record of roughly 500 to 800 CE in western Europe, meaning dark to us, not dark to live in.

The substance argues against the label. Universities at Bologna, Paris, and Oxford are medieval inventions. So are the mechanical clock, eyeglasses, the heavy plough, three-field rotation, blast furnaces, and the flying buttress. Meanwhile Baghdad's scholars, Al-Andalus, and Constantinople were producing mathematics, optics, and medicine that Europe later imported. A global "lights out" story requires ignoring most of the globe.

The fall of Rome was real, and in parts of the former western empire trade, literacy, and population genuinely contracted. That is worth teaching. The thousand-year blackout is not, and reference works and curricula have shifted to Early Middle Ages accordingly.
