To the east and to the west Andronicus II, utterly unable to defend himself, looked for aid. From this time on to the fall of Constantinople the history of the Byzantine Empire becomes what the history of the Ottoman Empire has been during the last hundred years. It is the story of an uninterrupted succession of bitter internal quarrels, of attacks by former vassals upon the immediate frontiers of its shrunken territory, of subtle undermining by hostile colonies of foreigners whose one thought was commercial gain, and of intermittent, and in almost all cases selfishly inspired, efforts of western Europe to put off the fatal day.

In the east, Andronicus expected much of Ghazan Khan. Were not the Turks of Asia Minor vassals of the Mongol overlord? Andronicus sent envoys to Ghazan to offer him the hand of a young princess who passed at Constantinople as his natural daughter. Ghazan received them cordially, accepted the proffered marriage alliance, and promised to exercise a pressure upon the Turks of western Asia Minor.[51] This promise, however, was not followed by any serious action. The Mongols were never more than mere raiders in Asia Minor.[52] Before this marriage could be consummated, Ghazan Khan died. The young princess was offered to and accepted by his successor. It was a useless sacrifice. For in this first decade of the fourteenth century the long struggle between Christian and Moslem to win the Mongols ended, temporarily at least, in the conversion of the Khans to Islam.[53]

From the west, Andronicus received aid of the most disastrous sort. When Ferdinand of Aragon made peace with Charles d’Anjou, King of Sicily, in 1302, he got rid of his troublesome mercenaries by sending them to serve the Byzantine Empire. Roger de Flor, typical soldier of fortune, who could not be matched in his generation for daring, insolence, rapacity, cruelty, and Achillean belief in his own invulnerability, arrived at Constantinople with eight thousand Catalans and Almogavares, the former heavy-armed plainsmen and mariners, the latter light-armed mountaineers of northern Spain. They were true prototypes of the soldiers of Alva and Cortes. Roger was made Grand Duke, and married to Princess Marie, niece of Andronicus.

Almost immediately after their arrival, the Catalans became engaged in such bloody conflicts with the Genoese of Galata, and robbed and murdered the Greeks with such alacrity, that Andronicus hastened to turn them loose in Asia. Roger established himself in the peninsula of Cyzicus. Here his Catalans fell immediately to plundering the inhabitants of the country, who soon found that they had passed from Scylla to Charybdis, and carried heartrending tales of lust and greed and massacre to Constantinople.[54] The one Greek general who was doing anything noteworthy against the Turks was relieved of his spoils of war by Roger.

In 1305, by a swift march to the relief of Philadelphia, which was being besieged by Alisur, prince of Karamania, Roger and his Catalans showed what they could do, if they would. The Turks were compelled to raise the siege. Roger pursued them to the source of the Sangarius.[55] But, on the way, the Catalans deprived their Greek allies of any portion of the rich spoils, and massacred the Slavic mercenaries who dared to argue with them.[56] Gregoras says, probably with reason, that Roger could have reconquered the whole of Asia Minor for the Byzantines.[57] But that country seemed to attract him as little as it had attracted the Mongols. He was no Crusader, glad and eager to undergo the terrible hardships which military operations among mountains and on arid plateaus demanded. There was no motive to make the effort worth while. So he left the Turks to themselves and went to Gallipoli, where he let it be known that the Catalans were preparing an expedition to repeat the Fourth Crusade.

In fear for his life as well as for his throne, Andronicus sent an envoy to offer Roger the ‘government of the Orient’, general command of all the troops in Asia, and twenty thousand pieces of gold. For full measure he added enough wheat to nourish the Catalans for a year. The ‘government of the Orient’ was as empty and meaningless a gift as the supposed ‘grants’ of the Seljuk Sultan Alaeddin to the Turkish nomad chieftains. The only troops who could go into Asia and accomplish anything were already under Roger’s command. But the gold, which might have worked a charm, was left behind, as the envoy was afraid to bring it. Roger scorned the emperor’s offer. Ten days later he repented, and accepted from Emperor Andronicus thirty thousand pieces of gold, one hundred thousand measures of wheat, and the title of Caesar. In return for these princely gifts he had only to promise to lead three thousand men against the Turks.

But a host of Spaniards, long before the discovery of America, were already in search of ‘El Dorado’. They poured into Gallipoli on every merchant ship from the West, and made the Byzantines begin to fear Roger more than they feared the Turks. The remedy was getting to be worse than the evil! Before leaving for his campaign, Roger rashly went to Adrianople to pay his respects to the young Emperor Michael IX, who was holding his court there. On the threshold of Michael’s bedchamber, like the Duke of Guise at Blois, he was stabbed to death. A massacre of his attendants followed.

A train of evils fell upon Macedonia and Thrace as a result of the assassination of Roger de Flor. Michael soon had reason to regret this ill-advised deed. Not only did the Catalans, in their first access of fury, avenge the death of their great leader and their comrades by unspeakable cruelties and by the destruction of every village which they came upon, not only did they defeat the young emperor in open battle and almost capture him as he fled from the field, but they invited over from Asia Minor into Macedonia all the Turks who could be induced to come.

At Gallipoli the Catalans tried to form a state. It failed owing to dissensions among their leaders. Their raids into Thrace had so ruined that country that they themselves began to starve. So they started upon an odyssey into Macedonia, where the common soldiers, wearied of the civil strife engendered by their leaders, who were continually ordering them to cut each other’s throats, decided to make an end of these costly personal jealousies. They killed the nobles who led them, and marched south into Thessaly. Gauthier de la Brienne committed the imprudence of seeking their aid in Athens. In 1310 they killed Brienne, set up in Athens a military democracy, and started to revive the Peloponnesian Wars.[58]

The further fortunes of the Grand Catalan Company do not come within the limits of our work. Roger and the Catalans, for that matter, were never in direct contact with the Osmanlis. But it was necessary to give a brief statement of their services to the Byzantine Empire in order that we might have a proper appreciation of their services to the Ottoman Empire. When they withdrew into Thessaly they had left the Turks behind them in Thrace and Macedonia. To the unhappy emperor who had received them nine years before as saviours of the Empire, this was their legacy.
