North Germanic peoples
Vikings were also active in Francia. Some of these Vikings would sail through the Strait of Gibraltar and pillage the coasts of the Mediterranean Sea. In the early 10th century, a group of Vikings under the leadership of Rollo settled in Rouen, France, and established the Duchy of Normandy. The descendants of these Vikings, known as the "Normans", would in the 11th century conquer England, Southern Italy, and North Africa, and play a leading role in launching the Crusades. Sub-groups of the Normans include Anglo-Normans, Scoto-Normans, Cambro-Normans, Hiberno-Normans and Italo-Normans.
Salme ships
According to an early interpretation offered by Jüri Peets, the lead archaeologist at the site, the ships and the dead are of Scandinavian origin. According to the most likely scenario, a war party of Scandinavians attempted to carry out a raid against the Oeselians (Estonian inhabitants of the island of Saaremaa), but were attacked by Oeselian ships. The sides of the two ships contain numerous embedded arrowheads, some of which are of the three-pointed type used to carry burning materials to set enemy ships aflame. After losing too many oarsmen to the Estonian archers, the raiders pulled their ships aground and tried to defend themselves behind them. It appears that after the battle, the Oeselians allowed either the survivors or some other group of Scandinavians to ritually bury their dead. The burial is unusual because the ships were not covered with earth mounds. The site was eventually forgotten by the local inhabitants after it had become overblown by sand and covered with vegetation. The raid-hypothesis has led to a questioning of when the Viking Age began exactly. The Salme event took place 50-100 years earlier than the infamous Lindisfarne Viking raid in England in the summer of AD 793.
