12. The Byzantine Vikings

Mercenary units are usually ad hoc affairs of adventurers from all over, gathered together under a captain for a specific mission, campaign, or war. As such, mercenary units seldom last for more than a few years before they are disbanded, once the conflict that gave rise to their creation is concluded.

The Byzantine emperors’ Varangian Guard, composed of Vikings, were an exception to that rule. Their history as a mercenary unit lasted for hundreds of years, stretching from the early tenth to the fourteenth centuries.
