BIOGRAPHICAL DOSSIER
Life and historical role
Life and political setting
Baldwin was a powerful northern French noble who united the counties of Flanders and Hainaut in 1195. He took the cross in 1200 and led one of the largest contingents of the Fourth Crusade. He should not be confused with King Baldwin I of Jerusalem, who died in 1118.
Role in the Crusades
After the capture of Constantinople in April 1204, an electoral college of crusade leaders and Venetians chose Baldwin emperor; he was crowned in Hagia Sophia on 16 May 1204. In conflict with the Bulgarian tsar Kaloyan and the Greek aristocracy of Thrace, the emperor was defeated and captured before Adrianople in April 1205 and died soon afterwards at Tarnovo.
Historical significance and source problems
Baldwin's short reign showed that the Latin Empire was militarily and politically fragile from its founding. The circumstances of his death are unclear; Villehardouin, Niketas Choniates and Akropolites give different accounts. A false “Baldwin” who appeared in Flanders years later exploited this uncertainty.
