Louis IX and his Holy relics

"In 1236, the Latin emperor of Constantinople, Baldwin II, approached the West for help in defending his moribund empire, one of the Latin States of Greece, born of the diversion of the fourth crusade in 1204. Early in 1237 he went to meet the French king Louis IX in Paris, telling him that, having run out of resources, he was obliged to borrow money against the relics with which Constantinople was still crammed, even after its sacking of 1204. Owing to his inability to repay the loans, these relics were at risk of falling into his creditors hands. On two occasions Louis IX redeemed the pledge.
