be disqualified from succeeding. (The Act was repealed in 1863.) Scotland The House of Stewart (later Stuart) had ruled in Scotland since 1371. It followed strict rules of primogeniture. After the union of the crowns Stuarts Elizabeth I of England and Ireland was succeeded by King James VI of Scotland, her first cousin twice removed, even though his succession violated Henry VIII's will, under which Lady Anne Stanley, heiress of Mary Tudor, Duchess of Suffolk, was supposed to succeed. James asserted that hereditary right was superior to statutory provision and, as King of Scotland, was powerful enough to deter any rival. He reigned as James I of England and Ireland, thus effecting the Union of the Crowns, although England and Scotland remained separate sovereign states until 1707. His succession was rapidly ratified by Parliament. James's eldest surviving son and successor, Charles I, was overthrown and beheaded in 1649 and the monarchy was abolished. A few years later, it was replaced by the Protectorate under Oliver Cromwell, a de facto monarch with the title of Lord Protector rather than King. Cromwell had the right to name his successor, which he exercised on his deathbed by choosing his son, Richard Cromwell. Richard was ineffective and was quickly forced from office. Shortly afterwards, the monarchy was restored, with Charles I's son Charles II as King. James II and VII, a Roman Catholic, followed his brother Charles II, despite efforts in the late 1670s to exclude him in favour of Charles's illegitimate Protestant son, the Duke of Monmouth. James was deposed when his Protestant opponents forced him to flee from England in 1688. Parliament then deemed that James had, by fleeing the realms, abdicated the thrones and offered the Crowns not to the King's infant son James but to his Protestant daughter Mary and to her husband William, who as James's nephew was the first person in the succession not descended from him. The two became joint Sovereigns (a unique circumstance in British history) as William III of England and Ireland (and II of Scotland) and Mary II of England, Scotland and Ireland. William had insisted on this unique provision as a condition of his military leadership against James. The English Bill of Rights and the Scottish Claim of Right Act, both passed in 1689, determined succession to the English, Scottish and Irish Thrones. First in the line were the descendants of Mary II.
