The Ninth Crusade
Within a year of the failure of the eighth crusade, Prince Edward of England, soon to be Edward I following the death of Henry III, landed in Acre, accompanied by Charles of Anjou, brother of the late King of France. Due to their lack of numbers, Edward attempted to make an alliance with the Mongul ruler of Persia, Abagha, which was greeted favourably. In an answer dated 4 September the Mongul ruler agreed to assist in withstanding the Mamluk attack. Strengthened by extra men from England and Cyprus, a force of 10,000 Monguls came to Syria, leading to a Mamluk withdrawal south. However, the Mongul withdrawal north soon led to a counter charge. The Sultan, Baibars, became discouraged believing a joint sea and land attack on Egypt was imminent, convincing him not to persevere. After successful defence of Cyprus, Edward agreed a peace treaty of 10 years, 10 months and 10 days with the Sultan and travelled home in 1273 on hearing news of the death of his father.
