R. was governed by vicars or apostolic administrators. From 1748 to 1850 R. was united with the diocese of Cloyne.
Among the diocese’s most notable bishops were Thaddeus Mc Carthy (1482–88), who died at Ivrea in 1492 and was beatified in 1895; Thomas O’Herlihy (1562–80), of great holiness, who suffered greatly for the Catholic faith and took part in the Council of Trent; Owen Mc Egan, who died for the faith in 1602; and Boetius Mc Egan, who was hanged at Carrigadrohid in 1650. With the consecration of William Keane as bishop of R. in 1851, the diocese regained its autonomy. Bishop Michael O’Hea took part in the First Vatican Council in 1869. The cathedral church is at Skibbereen.
