"As a Protestant descendant of Queen Victoria through her daughter the Empress Victoria of Germany, Georg Friedrich was in the line of succession to the British throne from his birth until his marriage in 2011; as he married a Roman Catholic, according to the Act of Settlement of 1701, he was thus debarred from the British line of succession until the implementation in 2015 of the Succession to the Crown Act 2013, which restored any succession rights to British dynasts forfeited because of marriage to Roman Catholics."
