BIOGRAPHICAL DOSSIER
Life and historical role
Life and political setting
Louis became king of France as a child in 1226 and grew up under the regency of his mother, Blanche of Castile. He became known for personal piety, judicial reform and the strengthening of royal administration. After recovering from a serious illness he took a crusading vow and organised an expedition on an unusually large royal scale.
Career during the Crusading era
Louis captured Damietta in 1249, but his army was worn down around Mansurah and his brother Robert of Artois was killed. Captured after the defeat at Fariskur in April 1250, Louis was released for a large ransom and the return of Damietta. He strengthened the defences of Acre in 1250–1254 and died of disease before Tunis in 1270.

Sources and historiography
Papal letters, conciliar canons and preaching texts record normative aims, while chronicles describe their social reception. Later versions of speeches are not verbatim minutes and should be compared through their shared provisions, date and circulation.
Names and titles vary between languages; Saint Louis should be searched together in catalogues and texts. Approximate dates remain marked as such, and later literary or visual fame is separated from contemporary testimony.
Biographical statements are tied to the sources listed on this page and to the connected event dossiers. Approximate or disputed dates remain marked; missing information is not filled by conjecture, and later literary or visual representations are not treated as contemporary portraits.
