On 6 January 1186, Marie and Baldwin were married at Valenciennes.[5]
The young countess consort issued charters in her own name and seems to have a soft spot for the cities in Flanders.[6] In 1200 she and her husband also released the Ninove and Bohéries Abbey from every toll on their territory.[6]
In 1200, she and her husband took the cross in Bruges.[7] On 14 April 1202 her husband left Flanders to join the Fourth Crusade.[8] During her husband's absence, Marie acted as regent for Flanders[6] for two years.
Marie herself left Flanders to join her husband in Outremer. According to Geoffrey of Villehardouin and other authors she could not join him in the crusade earlier as she was pregnant at the time of his departure.[9] After delivery of the child, Margaret and sufficient recovery, she set forth to join him.[10]
Latin Empress
Her husband's Crusade was diverted to Constantinople, capital of the Roman Empire, where the crusaders captured and sacked the city. Then the Crusaders and Venetian established the Latin Empire of Romaniae in place of the fallen one. On 9 May 1204, Baldwin was elected its first Emperor, making Marie the Empress.
She set sail from the port of Marseille and landed in Acre.[9] It was only when she arrived in Outremer that the news reached her of the fall of Constantinople and the election of Baldwin as the new Emperor of the East. There as an Empress of Constantinople she received the homage of the Prince Bohemond IV of Antioch.[11] She wanted to set sail for Constantinople but fell sick and died in the Holy Land.[9]
News of her death reached Constantinople through Crusading reinforcements from Syria. Baldwin was reportedly afflicted by the death of his wife.[10] Villehardouin reports that Marie "was a gracious and virtuous lady and greatly honoured".[10]
