Undaunted by the might of the Arab caliphates and the Byzantine Empire, they founded Russia, originated the bloodline that came to rule France, and created a North Sea empire that included England. They also established settlements across the North Atlantic, notably in Iceland and Greenland, and their adventurous spirit and extraordinary seafaring skills led them to explore and briefly build colonies in North America. These were the Vikings, initially ferocious pagan warriors seeking land and booty under the banners of their gods, but eventually belligerent Christian kings commanding vast armies. Martin Arnold provides a lively and accessible account of the early medieval period that became known as the Viking Age. Drawing on rich literary and archaeological source material, Arnold vividly illustrates the two faces of the Vikings: on the one hand, savage, greedy, and implacable; on the other, adventurous, innovative, and artistic.
