Theodore died in 1222. The first duty of the Greeks when driven out of Constantinople was to make themselves secure against the conquerors and to prevent the progress of the crusading armies into Asia Minor. This duty had been effectually done by Theodore. During the eighteen years of his reign he had made his capital and its beautiful neighbourhood the rallying-place of what was best in the Greek-speaking populations of Asia Minor and of Thrace. He had checked the progress of the crusaders into Asia Minor and had left to his successors the task of working for the recovery of Constantinople.
Henry succeeds Baldwin, 1205–1216.
Meantime, the history of the Latin conquerors of Constantinople had been one of almost continuous disaster. The first Emperor Baldwin had been lost in an encounter with the Bulgarians near Adrianople in April 1205, and was probably killed. As his fate remained doubtful, his brother Henry acted as regent for a year and was then crowned emperor. Shortly after the commencement of his reign in 1207, Boniface, Marquis of Montferrat and King of Salonica, was killed in a skirmish. Henry seems to have realised that in a policy of conciliation towards the Greeks lay the only hope of the continuance of his empire. He made peace with the Bulgarians and concluded an arrangement with both the emperor of Nicaea and the Greek prince who had made himself recognised as despot in Epirus. He employed Greeks in the public service. He refused to take part in the persecution of the Greeks who would not obey the decrees of the pope’s legate. He allowed them to employ the Greek language in their services, and restrained the pretensions of the Roman priests. Unfortunately for the Latin empire, the reign of the chivalrous Henry lasted only ten years.
Peter succeeds, 1217–1219.
He was succeeded by Peter of Courtenay, who was invited by the barons to occupy the throne in the absence of male heirs of Baldwin and his brother Henry. Peter left France with 140 knights and 5,500 men at arms, whom he had obtained with the aid of his royal kinsman, Philip Augustus. The reports of the rich plunder which had been obtained in the capture of the city had already induced many French knights to leave their native lands to take service in the empire, but the detachment with which Peter crossed the Alps was the largest which had left the West for such purpose.
The Venetians bargained to transport them across the Adriatic on condition that they would assist in recovering Durazzo from Theodore, the Greek despot of Epirus. After a useless assault on that city, Peter started with his followers on a journey across the peninsula to Salonica. He and his host were soon lost amid the mountains of Epirus. Their provisions were exhausted. They found the passes fortified, and their only chance of life was to surrender to Theodore, who had held the country in defiance of the regent who was governing in the name of the son of Boniface. Peter was detained in captivity, and his death is as mysterious as that of the first Latin emperor. He probably perished in prison in 1218.
Robert, 1219–1228.
Peter’s successor, Robert of Courtenay, succeeded in finding his way to Constantinople, though not across Macedonia, accompanied by a number of troops furnished at the request of Pope Honorius the Third. His reign was a series of disasters. He made a treaty of peace with Theodore of Nicaea in order that he might devote all his attention to the defeat of the other Theodore, the despot of Epirus. The latter had been denounced by the pope for his detention of Peter and of the legate who accompanied him. Honorius indeed had invited the princes of the West to undertake a crusade for their deliverance. When, however, the legate was released, Peter seems to have been forgotten. The despot Theodore made a well-concerted attack upon Salonica, captured it, and was proclaimed emperor in 1222. Robert led all his forces against this new claimant for the imperial title and was badly beaten. Theodore pushed on to Adrianople and hoisted his standard on the walls of that city almost without opposition.
There were thus in 1222 four persons claiming to be emperors, and occupying separate portions of what had been twenty years earlier the Roman Empire in the East. These were Robert at Constantinople, Theodore at Nicaea, another Theodore at Salonica, and Alexis at Trebizond.
Nicaea, success of John Ducas Vataces, 1222–1254.
