Bulgars and Vlakhs (roi de Blaquie et de Bougrie, in the words of Villehardouin), with Basil as primate, and they were both duly consecrated and crowned by the papal legate at Tirnovo in 1204. The French, who had just established themselves in Constantinople during the fourth crusade, imprudently made an enemy of Kaloian instead of a friend, and with the aid of the Tartar Kumans he defeated them several times, capturing and brutally murdering Baldwin I. But in 1207 his career was cut short; he was murdered while besieging Salonika by one of his generals who was a friend of his wife. After eleven years of further anarchy he was succeeded by John Asen II. During the reign of this monarch, which lasted from 1218 till 1241, Bulgaria reached the zenith of its power. He was the most enlightened ruler the country had had, and he not only waged war successfully abroad but also put an end to the internal confusion, restored the possibility of carrying on agriculture and commerce, and encouraged the foundation of numerous schools and monasteries. He maintained the tradition of his family by making his capital at Tirnovo, which city he considerably embellished and enlarged.

Constantinople at this time boasted three Greek emperors and one French. The first act of John Asen II was to get rid of one of them, named Theodore, who had proclaimed himself basileus at Okhrida in 1223. Thereupon he annexed the whole of Thrace, Macedonia, Thessaly, and Epirus to his dominions, and made Theodore's brother Manuel, who had married one of his daughters, viceroy, established at Salonika. Another of his daughters had married Stephen Vladislav, who was King of Serbia from 1233-43, and a third married Theodore, son of the Emperor John III, who reigned at Nicaea, in 1235. This daughter, after being sought in marriage by the French barons at Constantinople as a wife for the Emperor Baldwin II, a minor, was then summarily rejected in favour of the daughter of the King of Jerusalem; this affront rankled in the mind of John Asen II and threw him into the arms of the Greeks, with whom he concluded an alliance in 1234. John Asen II and his ally, the Emperor John III, were, however, utterly defeated by the French under the walls of Constantinople in 1236, and the Bulgarian ruler, who had no wish to see the Greeks re-established there, began to doubt the wisdom of his alliance. Other Bulgarian tsars had been unscrupulous, but the whole foreign policy of this one pivoted on treachery. He deserted the Greeks and made an alliance with the French in 1237, the Pope Gregory IX, a great Hellenophobe, having threatened him with excommunication; he went so far as to force his daughter to relinquish her Greek husband. The following year, however, he again changed over to the Greeks; then again fear of the Pope and of his brother-in-law the King of Hungary brought him back to the side of Baldwin II, to whose help against the Greeks he went with a large army into Thrace in 1239. While besieging the Greeks with indifferent success, he learned of the death of his wife and his eldest son from plague, and incontinently returned to Tirnovo, giving up the war and restoring his daughter to her lonely husband. This adaptable monarch died a natural death in 1241, and the three rulers of his family who succeeded him, whose reigns filled the period 1241-58, managed to undo all the constructive work of their immediate predecessors. Province after province was lost and internal anarchy increased. This remarkable dynasty came to an inglorious end in 1258, when its last representative was murdered by his own nobles, and from this time onwards Bulgaria was only a shadow of its former self.

The Serbian Supremacy and the Final Collapse, 1258-1393

From 1258 onwards Bulgaria may be said to have continued flickering until its final extinction as a state in 1393, but during this period it never had any voice in controlling the destinies of the Balkan peninsula. Owing to the fact that no ruler emerged capable of keeping the distracted country in order, there was a regular chassé-croisé of rival princelets, an unceasing tale of political marriages and murders, conspiracies and revolts of feudal nobles all over the country, and perpetual ebb and flow of the boundaries of the warring principalities which tore the fabric of Bulgaria to pieces amongst them. From the point of view of foreign politics this period is characterized generally by the virtual disappearance of Bulgarian independence to the profit of the surrounding states, who enjoyed a sort of rotativist supremacy. It is especially remarkable for the complete ascendancy which Serbia gained in the Balkan peninsula.

A Serb, Constantine, grandson of Stephen Nemanja, occupied the Bulgarian throne from 1258 to 1277, and married the granddaughter of John Asen II. After the fall of the Latin Empire of Constantinople in 1261, the Hungarians, already masters of Transylvania, combined with the Greeks against Constantine; the latter called the Tartars of southern Russia, at this time at the height of their power, to his help and was victorious, but as a result of his diplomacy the Tartars henceforward played an important part in the Bulgarian welter. Then Constantine married, as his second wife, the daughter of the Greek emperor, and thus again gave Constantinople a voice in his country's affairs. Constantine was followed by a series of upstart rulers, whose activities were cut short by the victories of King Uro[)s] II of Serbia (1282-1321), who conquered all Macedonia and wrested it from the Bulgars. In 1285 the Tartars of the Golden Horde swept over Hungary and Bulgaria, but it was from the south that the clouds were rolling up which not much later were to burst over the peninsula. In 1308 the Turks appeared on the Sea of Marmora, and in 1326 established themselves at Brussa. From 1295 to 1322 Bulgaria was presided over by a nobleman of Vidin, Svetoslav, who, unmolested by the Greeks, grown thoughtful in view of the approach of the Turks, was able to maintain rather more order than his subjects were accustomed to. After his death in 1322 chaos again supervened. One of his successors had married the daughter of Uro[)s] II of Serbia, but suddenly made an alliance with the Greeks against his brother-in-law Stephen Uro[)s] III and dispatched his wife to her home. During the war which ensued the unwonted allies were utterly routed by the Serbs at Kustendil in Macedonia in 1330.

From 1331 to 1365 Bulgaria was under one John Alexander, a noble of Tartar origin, whose sister became the wife of Serbia's greatest ruler, Stephen Du[)s]an; John Alexander, moreover, recognized Stephen as his suzerain, and from thenceforward Bulgaria was a vassal-state of Serbia. Meanwhile the Turkish storm was gathering fast; Suleiman crossed the Hellespont in 1356, and Murad I made Adrianople his capital in 1366. After the death of John Alexander in 1365 the Hungarians invaded northern Bulgaria, and his successor invoked the help of the Turks against them and also against the Greeks. This was the beginning of the end. The Serbs, during an absence of the Sultan in Asia, undertook an offensive, but were defeated by the Turks near Adrianople in 1371, who captured Sofia in 1382. After this the Serbs formed a huge southern Slav alliance, in which the Bulgarians refused to join, but, after a temporary success against the Turks in 1387, they were vanquished by them as the result of treachery at the famous battle of Kosovo in 1389. Meanwhile the Turks occupied Nikopolis on the Danube in 1388 and destroyed the Bulgarian capital Tirnovo in 1393, exiling the Patriarch Euthymus to Macedonia. Thus the state of Bulgaria passed into the hands of the Turks, and its church into those of the Greeks. Many Bulgars adopted Islam, and their descendants are the Pomaks or Bulgarian Mohammedans of the present day. With the subjection of Rumania in 1394 and the defeat of an improvised anti-Turkish crusade from western
