Middle English differed from Old English because of two invasions which occurred during the Middle Ages. The first invasion was by people who spoke North Germanic languages. They conquered and colonised parts of Britain during the 8th and 9th centuries AD. The second invasion was by the Normans of the 11th century, who spoke Old Norman and eventually developed an English form of this, called Anglo-Norman. A new vocabulary introduced at this time heavily influenced many organizations including the church, the court system and the government. European languages including German, Dutch, Latin and Ancient Greek influenced the English vocabulary during the Renaissance.
