The Early Medieval period is famous for Dark Ages England, but the rest of the world still existed in the Dark Ages - and for some civilisations, it wasn't even the Dark Ages but a Golden Age.
A map is essential for my research for my novels because I need to know where things came from and what routes were taken. Plus - I really love maps! ee the maps of Anglo-Saxon Britain.
So clearly the Dark Ages term is a misnomer everywhere in the world.
