In this period, in the lands corresponding to the current Lebanon were established several Latin ecclesiasticals, which most of the time they were supplanting ancient bishoprics of the early days of Christianity: the Archdiocese of Tyre from which depended the suffragan dioceses of Latin Catholic Bishop of Acre, Caesarea Philippi, Sidon and Berytus (modern Beirut), while from the Latin Patriarch of Antioch depended the suffragan dioceses of Byblos, Tripoli and Antarado.
These dioceses disappeared with the end of the Crusader period and remain today mostly as the venue owners.
[citation needed] The Latin continued presence in the country with the Friars Minor, who arrived as early as the thirteenth century, and then with missionaries of other religious orders, such as the Capuchin Friars, the Carmelites, the Vincentians and the Jesuits, who arrived in the seventeenth century.
For the faithful of the Latin Rite of Lebanon was not instituted any ecclesiastical district until the end of the French mandate at the end of World War II: the Apostolic Delegate (papal diplomatic envoy) of Syria held the functions of the bishop of the Latin Catholics of Lebanon.
The apostolic vicariate extends its jurisdiction over all Catholic faithful of the Latin Rite in Lebanon.
