Meanwhile, the succession crisis had prompted a mission to the west to seek assistance. In 1184, Patriarch Heraclius travelled throughout the courts of Europe, but no help was forthcoming. Heraclius offered the "keys of the Holy Sepulchre, those of the Tower of David and the banner of the Kingdom of Jerusalem", but not the crown itself, to both Philip II of France and Henry II of England; the latter, as a grandson of Fulk, was a first cousin of the royal family of Jerusalem, and had promised to go on crusade after the murder of Thomas Becket. Both kings preferred to remain at home to defend their own territories, rather than act as regent for a child in Jerusalem. The few European knights who did travel to Jerusalem did not even see any combat, since the truce with Saladin had been re-established. William V of Montferrat was one of the few who came to his grandson Baldwin V's aid.
