Saint Dominic established priories focused on study and preaching that became the Order's first "studia generalia", at the Parisian convent of St. Jacques in 1217, at Bologna in 1218, at Palencia and Montpellier in 1220, and at Oxford before his death in 1221. By 1219 Pope Honorius III had invited Dominic and companions to take up residence at the ancient Roman basilica of Santa Sabina, which they did by early 1220. In May 1220 at Bologna the Order's first General Chapter mandated that each convent of the Order maintain a "studium". The official foundation of the Dominican studium conventuale at Rome, which would grow into the "Angelicum", occurred with the legal transfer of the Santa Sabina complex from Pope Honorius III to the Order of Preachers on 5 June 1222.
