Abaqa died in 1282 and was briefly replaced by his brother Tekuder, who had converted to Islam. Tekuder reversed Abaqa's policy of seeking an alliance with the Franks, offering instead an alliance to the Mamluk Sultan Qalawun, who continued his own advance, capturing the Hospitaller fortress of Margat in 1285, Lattakia in 1287, and the County of Tripoli in 1289. However, Tekuder's pro-Muslim stance was not popular, and in 1284, Abaqa's Buddhist son Arghun, with the support of the Great Khan Kublai, led a revolt and had Tekuder executed. Arghun then revived the idea of an alliance with the West, and sent multiple envoys to Europe.
