During the reign of Queen Anne, Parliament settled the rules of succession in the Act of Settlement 1701, defining Sophia of Hanover (granddaughter of James VI and I) and her non-Catholic descendants as the future royal heirs. The Crown passed from Queen Anne to Sophia's son King George I as Sophia had already died. Queen Anne and King George I were second cousins as both were great-grandchildren of James VI and I.
