In 1172 Pedro Ruiz de Azagra, son of the Lord of Estella, took the city of Albarracín and succeeded in establishing a bishop there (Martín). Martín took the title of Arcabricense, and afterwards that of Segobricense, thinking that Albarracín was nearer to the ancient Segobriga (Segorbe) than to Ercavica or Arcabrica.
This choice of name follows the ideology of the Reconquest, according to which the bishops were simply restoring the old Christian entities only temporarily taken over by the Moors. In this way, the city of Albarracín became the seat of the bishops of Segorbe.
Diocese of Segorbe-Albarracín (1259–1571 or 1576)
When Segorbe was conquered by king Jaime I in 1245, its church was purified, and Jimeno, Bishop of Albarracín, took possession of it. The bishops of Valencia opposed this, and Arnau of Peralta, Bishop of Valencia, entered the church of Segorbe by force of arms. The controversy being referred to Rome, and the bishops of Segorbe had part of their territory restored to them; but the Schism of the West supervened, and the status quo continued.
