The Mongol Empire and the Rise of the Crusader States

The decline and ultimately the fall of the crusader states is a side effect of the wars of the Mamluks against the Mongols. In 1260, the Mongols invade Syria and destroy what's left of Saladin's dynasty, the Iuba Empire. And following this, the Mamluk's march out from Egypt incredibly boldly to confront the Mongols in battle. So when do we start to see the loss of the individual states of Adesar, Tripoli and Antioch? The Crusaders are destroyed as a sort of sideshow in that much bigger contest between these two other powers.
