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.
Swedes in the United Kingdom
The earliest wave of migration from modern day Sweden, Norway and Denmark came in the form of the Viking invasion of Britain in the year 793. Viking raids occurred up and down the largely undefended east coast of England and Scotland during the eighth and ninth centuries and Scandinavian settlements became established over the entire island of Great Britain, the most important of which was Jórvík (now York). Viking rule came to an end in the 11th century when Normans invaded the shores of Britain. Despite this, Scandinavian influence is evident in the UK even to this day and many millions of Britons have some Viking heritage (especially in Northern England, Eastern England, Scotland and the Shetland Islands).
