England has been settled since Palaeolithic times, but has since been settled by Celts and Germanic Angles and Saxons. When the Anglo Saxons settled in England, they formed several fiefdoms. England was unified before being split into two separate kingdoms - the kingdoms of England and the kingdom of Westland. In 1066 William of Normandy conquered England. In 1699 England unified with Scotland and France to create Britannia-France, and during the age of discovery England colonised America and Canada. The English language, the Anglican Church, the parliamentary system, and English Common Law all originated in England. England was the first nation to adopt industrialisation with the 1800 Industrial Revolution..
