Baldwin II’s Second Journey to Western Europe …

Baldwin II’s Second Journey to Western Europe (1245): The Sale of Relics to Louis IX

In 1245, Baldwin II, the struggling Latin Emperor of Constantinople, embarked on a second journey to Western Europe, seeking financial and military aid to support his weakening empire, which was under constant threat from the resurgent Byzantine forces of Nicaea. Lacking funds and desperate to secure support, Baldwin resorted to selling sacred relics that had been preserved in Constantinople, including some of the most revered objects in Christian tradition.


The Sale of Relics to Louis IX

  • Baldwin II sold a large collection of alleged relics, including:

    • The Crown of Thorns, believed to have been worn by Jesus Christ during His Crucifixion.
    • A large portion of the True Cross, supposedly the actual cross upon which Jesus was crucified.
    • Several other Holy Relics from Constantinople, which had been preserved in the Byzantine imperial treasury for centuries.
  • The buyer was King Louis IX of France, who was deeply pious and a dedicated crusader. He saw the acquisition of these relics as an extraordinary opportunity to enhance France’s spiritual prestige.


The Relics and the Sainte-Chapelle in Paris

  • Upon acquiring the relics, Louis IX built the Sainte-Chapelle in Paris (consecrated in 1248) as a magnificent reliquary to house them.
  • The Sainte-Chapelle was designed as a masterpiece of Rayonnant Gothic architecture, emphasizing light, height, and intricate stained glass to create a divine, ethereal atmosphere.
  • The relics were enshrined with great ceremony, and Paris became one of the most important pilgrimage sites in medieval Christendom.

Impact and Legacy of Baldwin II’s Actions

  1. Temporary Aid for the Latin Empire

    • The sale of relics provided Baldwin II with some immediate financial relief, but it was not enough to save the crumbling Latin Empire.
    • In 1261, the Byzantines recaptured Constantinople, marking the end of the Latin Empire.
  2. Elevating Paris as a Religious Center

    • The acquisition of the Crown of Thorns and other relics made Paris a new center of Christian devotion, rivaling Rome and Jerusalem.
    • The Sainte-Chapelle remains one of the greatest medieval Gothic monuments today.
  3. The Decline of the Latin Empire

    • The sale of Constantinople’s sacred relics symbolized the empire’s desperate decline.
    • It also weakened the Latin Church’s standing in the East, as Byzantine Christians viewed the Latin rulers as plunderers rather than protectors of Orthodoxy.

Baldwin II’s sale of relics in 1245 was a desperate financial maneuver that provided short-term aid but ultimately did little to save the Latin Empire, while simultaneously enhancing France’s religious and cultural prestige under Louis IX.
