Hebron was an episcopal see during the Crusader period.
Eusebius [1] (fourth century) calls Hebron merely as a large hamlet. It contains the tomb of the patriarchs, mentioned by Josephus, [2] by Eusebius, [3] and by the Pilgrim of Bordeaux in 333.
Crusaders took the town in 1100, and the sanctuary became the church of Saint Abraham, also called the church of the Holy Cave (Sancta Caverna or Spelunca, ’ágion spelaîon). The town itself is often styled by the chroniclers of that period Castel Saint-Abraham, Præsidium or Castellum ad Sanctum Abraham. A priory of Canons Regular of St. Augustine was installed to take charge of the basilica. [4]
In 1167 Hebron became a Latin see; its first titular was Rainaldus (1167–1170), nephew of the patriarch Foucher. [5]
A letter of Pope Clement IV, dated 1 June 1267, orders the Patriarch of Jerusalem to supply the church of Hebron with a priest. [6] After Geoffrey (Gaufridus), O.P., 1273–1283, the bishops of Hebron were merely titulars, and a great confusion existed in their list. [7] [8]
As a residential see, Hebron enjoyed a very brief existence. However it survived the triumph of Saladin in 1187, and the march of the Khwarezmians in 1244. Saladin, after the victory at Hattin (4 July 1187), and that at Ascalon (5 September), hastened, before marching on Jerusalem, to occupy Hebron, and to associate the sanctuary of Abraham with the worship of Islam. The Khwarezmians destroyed the town, but did not touch the sanctuary. [9]
The Greeks, after the departure of the Latins, retained for a time a residing bishop in Hebron. Lequien [10] mentions one of these bishops, Joannikios, whose name appears with that of Christodoulos of Gaza in the Acts of the Council of Jerusalem in 1672 [11] under the title of Ioannikíou toû theophilestátou ’archiepiskópou toû ‘agíon spelaíon (Joannikios, most holy Archbishop of the holy Cave).
In modern times, it was revived as a titular see; Cardinal Mermillod and Michele Petkoff, Vicar Apostolic of the Uniat Bulgarians in Thrace, were titular bishops.[ citation needed ]

The Latin Patriarchate of Jerusalem is the Latin Catholic ecclesiastical patriarchate in Jerusalem, officially seated in the Church of the Holy Sepulchre. It was originally established in 1099, with the Kingdom of Jerusalem encompassing the territories in the Holy Land newly conquered by the First Crusade. From 1374 to 1847 it was a titular see, with the patriarchs of Jerusalem being based at the Basilica di San Lorenzo fuori le Mura in Rome. Pope Pius IX re-established a resident Latin patriarch in 1847.
The Kingdom of Jerusalem, one of the Crusader states that was created in 1099, was divided into a number of smaller seigneuries. According to the 13th-century jurist John of Ibelin, the four highest crown vassals in the kingdom proper were the count of Jaffa and Ascalon, the prince of Galilee, the lord of Sidon, and the lord of Oultrejordain.
Toron, now Tibnin or Tebnine in southern Lebanon, was a major Crusader castle, built in the Lebanon mountains on the road from Tyre to Damascus. The castle was the centre of the Lordship of Toron, a seigneury within the Kingdom of Jerusalem, actually a rear-vassalage of the Principality of Galilee.
The principality of Galilee was one of the four major seigneuries of the crusader Kingdom of Jerusalem, according to 13th-century commentator John of Ibelin, grandson of Balian. The direct holdings of the principality centred around Tiberias, in Galilee proper, but with all its vassals, the lordship covered all Galilee and southern Phoenicia. The independent Lordship of Sidon was located between Galilee's holdings. The principality also had its own vassals: the Lordships of Beirut, Nazareth, and Haifa.
The See of Tyre was one of the most ancient dioceses in Christianity. The existence of a Christian community there in the time of Saint Paul is mentioned in the Acts of the Apostles.

Its position was briefly challenged by the see of Berytus in the mid-5th century; but after 480/1 the metropolitan of Tyre established himself as the first (protothronos) of all those subject to the Patriarch of Antioch.
