In 1205 the recently elected Emperor of Constantinople, Baldwin, Hereditary Count of Flanders and Hainault, was defeated and taken prisoner by Joannice, King of Bulgaria. The release of the illustrious captive was demanded by Pope Innocent the Third, but the barbarian victor contented himself with replying that Baldwin had died in prison. He did not condescend to furnish any particulars of his decease, but rumour supplied the omission by inventing and retailing all kinds of terrible tales of his murder, the most noteworthy of which the curious reader may find upon referring to the pages of Gibbon. The real circumstances of his death never came to light, but there does not appear to be the slightest reason for doubting the fact itself; the intelligence was credited by his allies and subjects, and nothing plausible has been advanced to account for Joannice asserting it if untrue. His brother Henry, however, who, upon the news of Baldwin's defeat and capture, had been appointed Regent, would not consent to receive the imperial crown until the lapse of a twelvemonth after the fatal intelligence; and the mystery with which the barbarian victor's prisons was enshrouded would appear to have inspired the Latins with a belief in the prolonged existence of their monarch. Be this as it may, twenty years passed away without any one appearing to question the fact of Baldwin's death. At the expiration of that period, when the sovereignty of Flanders and Hainault had devolved upon the Emperor-Count's eldest daughter Jean, a claimant appeared to assert his identity with the lost monarch. He maintained that after his capture at Adrianople he had been kindly treated by his Bulgarian captors, who, after a lapse of years, so far relaxed their watchfulness that he was enabled to effect his escape from custody; taken prisoner, however, by another barbarous tribe, unacquainted with his rank, he had been treated by them as a slave, and finally taken into Syria and sold. There for two years he had been compelled to toil as a common labourer. Enabled, by accident, to make himself known to some German merchants, who were permitted to trade in the vicinity, they had ransomed him for a small amount; and as by the death of his brother the throne of Constantinople had reverted to another, and probably hostile, branch of the family, he had deemed the recovery of his hereditary dominions an easier task than that of his Eastern empire.
