The war ended in 1453 when the English were finally ejected from France, but in the early 15th century the English under King Henry V made significant territorial gains. The Treaty of Troyes in 1420 made Henry V the heir apparent to the French throne but when the French king, Charles VI, and Henry V died in the space of two months in 1422 the issue of succession was again uncertain. The English supported Henry V's son, Henry VI who was still a child, while the French supported recognised Charles VII, the Dauphin of France.
Succession to the British throne Ireland. She was not universally recognised and after nine days she was overthrown by the popular Mary. As Henry VIII's will had been approved by an Act of Parliament in 1544, Edward's contravening will was unlawful and ignored. Mary was succeeded by her half-sister, Elizabeth, who broke with the precedents of many of her predecessors, and refused to name an heir. Whilst previous monarchs (including Henry VIII) had specifically been granted authority to settle uncertain successions in their wills, the Treasons Act 1571 asserted that Parliament had the right to settle disputes, and made it treason to deny Parliamentary authority.
