Egypt prospered exceedingly under his just, firm, and capable rule; he was severe to immorality and strictly prohibited wine, beer, and hashish. He entered into diplomatic relations with European powers to the great advantage of his country's trade; and his bravery, munificence, and justice have made him a popular hero in Arabic romances down to the present day. None of his successors approached his high example Khalil indeed recovered Acre and all that remained of the Crusader's possessions in Palestine, and the Mamluks, who never lost their soldierly qualities whoever happened to be their nominal ruler, handsomely defeated the Mongols again in 1299 and 1303, and for ever saved Egypt from the unspeakable curse of a Mongol conquest Nasir, whose reign covers most of the first half of the fourteenth century, was a great builder, and so were many of the nobles of his court. It was the golden age of Saracenic architecture, and Cairo is still full of the monuments of Nasir's emirs. He encouraged agriculture, stockbreeding, farming, falconry, as well as literature and art, everything, in short, except vice, wine, and Christians. The Burgi, or Circassian Mamluks (1382-1517), were little more than chief among the emirs. Widespread corruption, the open sale of high offices and of "justice," and general debauchery characterised their rule. Yet they built many of the loveliest mosques in Cairo, and the conquest of Cyprus, long a nest of Mediterranean piracy, by Bars Bey in 1426 may be added to their credit. Kait Bey (1468-1496) was a great builder, and in every way a wise, brave, and energetic, public-spirited sovereign, and was an exception to the general baseness. Egypt was rich in his day. The European trade had swelled enormously, and the duties brought in a prodigious revenue. The Italian Republics had their consulates or their marts in Alexandria, and Marseilles, Narbonne, and Catalonia sent their representatives. The Indian trade was also very considerable; we read of £36,000 paid at one time in customs dues at Gidda, then an Egyptian port on the Red Sea. The Mamluk sultan took toll on every bale of goods that passed between Europe and India in the palmy days that preceded Vasco de Gama's discovery of the Cape route in 1497. It was an immense monopoly, extortionately used, and it was not resigned without a struggle. The Mamluk fleet engaged the Portuguese off Chaul in the Bay of Bengal in 1508 and defeated them; but Almeida avenged the honour of his country by a victory over the Mamluk admiral Hoseyn off Diu in the following year, and the prolific transit trade of Egypt was to a great extent lost.
