Prince Edward, later known as Edward I of England, was heavily involved in the Ninth Crusade, which sought to recover the Holy Land from Muslim control. In the midst of his campaigns, he received the news of his father, King Henry III's death. The momentous news came from messengers who traveled to the Holy Land, impacting Edward's sense of duty and direction. Despite having been named king, Edward remained in the Levant, focusing on military strategy against the forces of Sultan Baibars. He pushed forward with the Crusade, leading his troops through various sieges and establishing temporary alliances with local rulers. Edward’s commitment to the Crusade showcased his dedication to the cause but also his willingness to postpone assuming the throne of England.

For nearly two years, the governance of England fell to regents while the new king was abroad. This period was significant as it prevented Edward from establishing his authority directly in England, leading to a range of political maneuverings at home. As a king-in-waiting, he had to navigate the delicate balance between his obligations as a crusader and the expectations of English noblemen eager for a strong ruler. His eventual return in 1274 would set the stage for significant political and military reforms in England.
