Longships on Restless Seas. The History of the Vikings, #2

For centuries, a fire swept through Europe. It raged on and on, putting nations and kingdoms at its mercy, and that fire came from the North. Due to a series of socio-political triggers, the Vikings emerged from their northern homes in Scandinavia and swept all across the realms of Europe - south, east, west, and north. Mastering the navigation of the oceans and dominating the riverways, these vicious Northmen embarked upon their swift longships and introduced an entirely new chapter of Europe's history.
