A concise history of the Vikings and their time by the Norwegian historian and author of Vikings at War.   From the ninth to the eleventh century, Viking ships landed on almost every shore in the Western world. Viking ravages united the Spanish kingdoms and stopped Charlemagne and the Franks’ advance in Europe. Employing sail technology and using unpredictable strategies, the Vikings could strike suddenly, attack with great force, then withdraw with stolen goods and captives. Wherever Viking ships roamed, enormous suffering followed in their wake, but the encounters between cultures changed both European and Nordic societies.   This short history of the Vikings introduces readers to this highly influential medieval society. Here you will learn how Vikings raided across Europe and even America, with fascinating information about their ships, weapons and armor, and unique way of life.
