At first, Emperor Louis confirmed the agreement reached in
Rheims with Paschal's predecessor, Stephen IV, and detailed in the document
Pactum Ludovicanum about free papal elections and noninterference in Church affairs unless officially asked for help. The two worked together to send Archbishop
Ebbo of Rheims to evangelize the
Danes in 822. On Easter Sunday of 823, Paschal
crowned and
anointed Louis's son
Lothair I. Lothair was less amenable to cooperating with the Papal Curia than his father. He held a court and declared
Farfa Abbey, just north of Rome, exempt from papal taxation. Paschal's aristocratic opponents in the papal palace, especially his former legate, Theodore, and his son-in-law, Leo, who turned to the young leader of the Franks for support in their opposition to Paschal. He both offered the exiled Byzantine mosaic artists work decorating churches in Rome and the Byzantine emperor
Leo the Armenian in support of those who opposed iconoclasm. These churches contain mosaics with lifelike portraits of Paschal. In addition, Paschal added two oratories to
Old St. Peter's Basilica, SS. Processus et Martinianus and SS. Xistus et Fabianus, which did not survive the 16th century renovation of St. Peter's. Paschal is also sometimes credited with the renovation of
Santo Stefano del Cacco in early modern sources, but this renovation was actually undertaken by
Pope Paschal II. According to Goodson, Paschal "used church-building to express the authority of the papacy as an independent state."
Writings of Paschal I Only six known letters written by Paschal remain. The first (Jaffé 2546) confirms the possessions of the
Territorial Abbey of Farfa. ==Death==
