The terms of the crusade were agreed through negotiations between the envoys of Baldwin II and the doge of Venice. Once the Venetians decided to participate, Pope Callixtus II sent them his papal banner to signify his approval, At the First Council of the Lateran he confirmed that the Venetions had crusader privileges, including remission of their sins.[4] The church also extended its protection to the families and property of the crusaders.[5]
