The House of Stuart is a European royal house. Founded by Robert II, the House of Stuart—also spelled Stewart in Scottish contexts—first became monarchs of the Kingdom of Scotland during the late 14th century before inheriting the kingdoms of England (including Wales) and Kingdom of Ireland in the 17th century. The dynasty's patrilineal Breton ancestors had held the office of High Steward of Scotland since the 12th century, after arriving by way of Norman England. In 1707, Queen Anne became the first monarch of the newly merged Kingdom of Great Britain.
