BIOGRAPHICAL DOSSIER
Life and historical role
Life and political setting
Born Lotario dei Conti di Segni in Italy, Innocent studied at Paris and Bologna and was elected pope in 1198. He developed a strong conception of papal monarchy that influenced European politics, canon law and missionary activity. Crusading under his pontificate became a more continuous institution supported by preaching, taxation and legal privileges.
Career during the Crusading era
Innocent called a new expedition in 1198, but Venetian debt diverted the Fourth Crusade first to Zara and then to Constantinople. He prohibited the attacks and used excommunication, yet after 1204 he accepted the resulting Latin order. At the Fourth Lateran Council in 1215 he secured detailed provisions for the finance and preparation of the Fifth Crusade.
