The English overseas possessions, also known as the English colonial empire, comprised a variety of overseas territories that were colonised, conquered, or otherwise acquired by the former Kingdom of England during the centuries before the Acts of Union of 1707 between the Kingdom of England and the Kingdom of Scotland created the Kingdom of Great Britain. The many English possessions then became the foundation of the British Empire and its fast-growing naval and mercantile power, which until then had yet to overtake those of the Dutch Republic, the Kingdom of Portugal, and the Crown of Castile. The first English overseas settlements were established in Ireland, followed by others in North America, Bermuda, and the West Indies, and by trading posts called "factories" in the East Indies, such as Bantam, and in the Indian subcontinent, beginning with Surat. In 1639, a series of English fortresses on the Indian coast was initiated with Fort St George. In 1661, the marriage of King Charles II to Catherine of Braganza brought him as part of her dowry new possessions which until then had been Portuguese, including Tangier in North Africa and Bombay in India. In North America, Newfoundland and Virginia were the first centres of English colonisation.

In 1664, New Netherland and New Sweden were taken from the Dutch, becoming New York, New Jersey, and parts of Delaware and Pennsylvania.

During the rule of the House of Knýtlinga, from 1013 to 1014 and 1016 to 1042, England was part of a personal union that included domains in Scandinavia. In 1066, William the Conqueror, Duke of Normandy, conquered England, making the Duchy a Crown land of the English throne. Through the remainder of the Middle Ages the kings of England held extensive territories in France, based on their history in this Duchy. Under the Angevin Empire, England formed part of a collection of lands in the British Isles and France held by the Plantagenet dynasty. The collapse of this dynasty led to the Hundred Years' War between England and France. At the outset of the war the Kings of England ruled almost all of France, but by the end of it in 1453 only the Pale
