[1][2] After the invasion of Italy by the Lombards, Teramo became the residence of a gastald, depending on the Duke of Spoleto; under the Franks it was annexed by the Normans.

Pope Clement VII dispensed Bishop Francesco Cherigatto from observing the custom in a brief of 15 January 1524; the practice was finally abolished in 1554.

In 1416 it was sacked by Lordino de Saligny, a Frenchman,[7] exasperated at being deprived of the title of High Constable of the kingdom of Naples.

As the capital of a province, Pescara deserved to become the seat of a bishop; but the city extended over two different dioceses, Chieti and Penne.

[11] Pope Pius XII therefore decided on the rearrangement of the diocesan system, which he effected in the Bull Dioecesium subscriptiones of 1 July 1949.

There was to be one episcopal curia, one ecclesiastical tribunal, one college of Consultors, one Council of Priests, and one seminary, all of which were at Teramo or a place designated by the bishop.
