"Kingdom of Greece". Such denials of Byzantium's Roman heritage and ecumenical rights would instigate the first resentments between Greeks and "Latins" (for the Latin liturgical rite) or "Franks" (for Charlemegne's ethnicity), as they were called by the Greeks. Popular Western opinion is reflected in the Translatio militiae, whose anonymous Latin author states that the Greeks had lost their courage and their learning, and therefore did not join in the war against the infidels. In another passage, the ancient Greeks are praised for their military skill and their learning, by which means the author draws a contrast with contemporary Byzantine Greeks, who were generally viewed as a non-warlike and schismatic people. While this reputation seems strange to modern eyes given the unceasing military operations of the Byzantines and their eight century struggle against Islam and Islamic states, it reflects the realpolitik sophistication of the Byzantines, who employed diplomacy and trade as well as armed force in foreign policy, and the high-level of their culture in contrast to the zeal of the Crusaders and the ignorance and superstition of the medieval West. As historian Steven Runciman has put it: "Ever since our rough crusading forefathers first saw Constantinople and met, to their contemptuous disgust, a society where everyone read and wrote, ate food with forks and preferred diplomacy to war, it has been fashionable to pass the Byzantines by with scorn and to use their name as synonymous with decadence". A turning point in how both sides viewed each other is probably the massacre of Latins in Constantinople in 1182. The massacre followed the deposition of Maria of Antioch, a Norman-Frankish (therefore "Latin") princess who was ruling as regent to her infant son Emperor Alexios II Komnenos. Maria was deeply unpopular due to the heavy-handed favoritism that had been shown the Italian merchants during the regency and popular celebrations of her downfall by the citizenry of Constantinople quickly turned to rioting and massacre. The event and the horrific reports of survivors inflamed religious tensions in the West, leading to the retaliatory sacking of Thessalonica, the empire's second largest city, by William II of Sicily. An example of Western opinion at the time is the writings of William of Tyre, who described the "Greek nation" as "a brood of vipers, like a serpent in the bosom or a mouse in the wardrobe evilly requite their guests".
