For hundreds of years, the Anglo-Saxons – who had been harassing the Saxon Shore as pirates –began to settle in Britain, creating a patchwork of little kingdoms and starting a new era of English history. Several early medieval historians, writing well after the events, said the Anglo-Saxons were invited to Britain to defend the region from the northern tribes and ended up taking over. The Venerable Bede (672 or 673-735) said in his Historia ecclesiastica gentis Anglorum (“Ecclesiastical History of the English People”) that in the year 449, “The British consulted what was to be done and where they should seek assistance to prevent or repel the cruel and frequent incursions of the northern nations. They all agreed with their king Vortigern to call over to their aid, from the parts beyond the sea, the Saxon nation. … The two first commanders are said to have been Hengist and Horsa.”

However they came to control most of England, the Anglo-Saxons became the dominant power in the region for nearly 500 years, and the strength of their cultural influence could be felt even after William the Conqueror won the Battle of Hastings and became the first Norman ruler on the island. William is one of history’s most famous conquerors, but the efforts to consolidate his rule in England were complicated from the start, both due to external enemies and those jockeying for his position while he was still alive. William ultimately decided to split Normandy and England. His son Robert, still in open revolt, would nonetheless inherit Normandy, while the next in line, his second son William, would rule England. The two states that William left behind were hardly united or at peace. Soon after his death, Odo conspired with Robert to oust his brother from the English throne and re-establish a united state, but the revolt failed, and King William “Rufus” II would rule England until his suspicious death in 1100.
