With the death of her brother-in-law William III in 1702, Princess Anne becomes Queen. She becomes a popular monarch, even if there are many Jacobites in Parliament who feel that she is not the true monarch. Her friendship with John and Sarah Churchill continues strong, naming John the Duke of Marlborough and providing for him with an annual income that befits his new rank. On the death of Queen Anne's father, the former King James II, King Louis XIV of France recognized James' son as the rightful monarch. This and the issue of the Spanish succession again leads to war with France. Marlborough's military successes continue and his role as head of the army brings endless victories on the battlefield.
