[1][2] In the 13th century the territory and city of Recanati became heavily involved in the struggles between Guelphs and Ghibbelines.

On 27 July 1263 the diocese was completely suppressed by Pope Urban IV in the Bull Cives Recanatensis, due to its support of Manfred, who claimed the Kingdom of Sicily.

[7] On 17 March 1586, Pope Sixtus V, in the Bull Pro excellenti, raised the town of Loreto to the status of a bishopric.

The changes were embodied in a decree of the Sacred Congregation of Bishops in the Roman Curia, promulgated on 30 September 1986.

[14] A diocesan synod was an irregularly held, but important, meeting of the bishop of a diocese and his clergy.

Its purpose was (1) to proclaim generally the various decrees already issued by the bishop; (2) to discuss and ratify measures on which the bishop chose to consult with his clergy; (3) to publish statutes and decrees of the diocesan synod, of the provincial synod, and of the Holy See.

[17] In 1687 Bishop Fabrizio Paolucci (1685–1698) had his Synodial Constitutions published, but it is uncertain when he held his synod.
