The cathedral was administered and staffed by a corporation called the Chapter, which was composed of four dignities (Archdeacon, Dean, Cantor and Archpriest) and sixteen canons.

Its purpose was:[7] Bishop Marco de Rama (1690–1709) presided over a diocesan synod in Crotone on 9 July 1693.

[10] On 20 December 1795, Bishop Ludovico Ludovici (1792–1797) held a diocesan synod, whose decrees were published in Naples in 1796.

[11] Bishop Leonardo Todisco Grande (1834–1849) began a general visitation of the institutions of his diocese in 1842,[12] and then presided over a diocesan synod which was held at Crotone on 1–3 June 1845; its constitutions and decrees were published.

[14] In the same concordat, the King was confirmed in the right to nominate candidates for vacant bishoprics, subject to the approval of the pope.

[15] Changing patterns of settlement and distribution of wealth following World War II had an impact on dioceses which were mostly rural in character.

Archbishop Michele Federici of Santa Severina was transferred to Veroli-Frosinone on 23 December 1973, which cleared the way to a reorganization of diocesan resources in Calabria.

Based on the revisions, a set of Normae was issued on 15 November 1984, which was accompanied in the next year, on 3 June 1985, by enabling legislation.

According to the agreement, the practice of having one bishop govern two separate dioceses at the same time, aeque personaliter, was abolished.

The provinces of Calabria were addressed by Pope John Paul II in the bull Maiori Christifidelium of 30 January 2001.
