This volume publishes the content of 133 charters of Saint Louis, issued in the East during his first crusade. They come from the Latin manuscript 9778 of the National Library of France, which went overseas with the monarch. These documents from 1248 to 1254 shed light on the operation of the royal household in the Levant. In particular, they highlight two prosperous periods in 1250 and 1252, which saw the king granting a series of privileges from Acre and Caesarea of Palestine, and allow us to follow the early careers of new men coming from the Holy Land and France.
