Studied at the University of Bologna, Italy. Dominican friar, receiving the habit from Saint Dominic de Guzman himself. At the General Chapter the Dominicans in Bologna in 1221, Sadoc was chosen to assist Master Paul of Hungary to establish a province in Hungary. Sadoc later moved on to Poland where he served as preacher for nearly forty years. In 1260 he and eight Dominicans from Sandomierz were martyred by the Tartars as they were singing the Salve Regina at Compline; the custom of singing the Salve Regina at the deathbed of Dominicans stems from this incident.
Lord Jesus, in the midst of fierce attacks of the foe Blessed Sadoc and his companions greeted the Virgin Mary in song and received the longed-for palm of martyrdom. After this exile may your merciful and loving Mother show us to you, who live and reign in the unity of the Holy Spirit, one God, for ever and ever. - Dominicans
