Sixteen hundred years ago Britain left the Roman Empire and swiftly fell into ruin. Grand cities and luxurious villas were deserted and left to crumble, and civil society collapsed into chaos.

It explains how their earliest rulers fought relentlessly against each other for glory and supremacy, and then were almost destroyed by the onslaught of the vikings.
