Ragnar Loðbrók ("Hairy Breeches") was one of the most feared Vikings active in France and England in the Ninth Century. His sons conquered England and his descendants, properly called the Ragnarætten , established several influential dynasties. During the Tenth Century, grandsons and great-grandsons of Ragnar founded kingdoms in Ireland and Continental Europe. Their well-timed marriages over the next several centuries ensured that the progeny of Ragnar would play a great part in Europe's politics for a very long time. Key:
