Until the early twelfth century, the Kingdom of Meath had been divided into eight small monastic episcopal sees, which were located at Clonard, Duleek, Kells, Trim, Ardbraccan, Dunshaughlin, Slane, and Fore. By the time of the Synod of Rathbreasail, held in 1111, the last five had been united to the see of Clonard. Duleek was still recognized as a separate bishopric at the Synod of Kells, held in 1152, but disappeared not long after that date. The see of Kells was ruled together with Breifne (later Kilmore) in the second half of the twelfth century, but after 1211 Kells was incorporated into the diocese of Meath.
During the twelfth century, the bishops of Clonard were frequently called the "bishop of Meath" or "bishop of the men of Meath". Bishop Simon Rochfort transferred his seat from Clonard to Trim in 1202 and the title "bishop of Meath" became the normal style.
