1066 is a common year in the Gregorian calendar and the Anno Domini (common) era. It is the 66th year of the 11th century and the 2nd millennium. The year is considered by many historians to be a turning point in history due to various events (see below), particularly the Battle of Hastings and ensuing Norman conquest of England, with years prior to 1066 being the late Dark Ages and years after 1066 being the Middle Ages.[1] This was the last successful hostile invasion of Great Britain.
