Because one of the important branches of Christianity, Coptic Orthodox Church, is mainly distributed in Egypt and Ethiopia.

The Pope/Church was originally a papal state in Rome, with a large area of land in central Italy and a large number of papal schools in Rome. During the founding of Italy, the Pope's territory was limited to castles, and these schools were placed outside the country. There is only Ethiopian Academy of Sciences in the castle, because it is a small building, but it just stays in the territory. It is called Ethiopian College because it was built for monks and priests in Ethiopia. ?

First of all, the Vatican is not a conventional country, but a product of the compromise of religious forces during the founding of Italy in the19th century. /kloc-in the 0 th and 9 th centuries, the armed forces were unified throughout Italy. Like other small countries, this land was confiscated, and only the Vatican Castle was left to the Pope as an independent territory. At present, the actual power and influence of the Vatican depends on the church institutions and believers all over the world, and has nothing to do with the land area. Therefore, the expansion or contraction of the area is not the key issue. Note: The official Chinese translation of the church is Pope, which is a common translation and usually does not need special correction. ?

There are many other Pontifical Universities and Pontifical Colleges in Rome, which are numerous and occupy a large area. When Italy was founded, the Pope's territory was limited to castles, so the whole city of Rome and other lands belonged to Italy. Naturally, those schools are no longer in the Vatican. However, the Apostolic School is still under the jurisdiction of Catholicism. This Ethiopian college is located in the Vatican Castle because it has been small since its establishment. This is a very small institution. I gave it to a small building nearby and didn't move. When Italy removed other lands of the papal state, it was still lucky to remain. The Catholic Church has an institution called the Ministry of Education, and its directly affiliated undergraduate theological university is called the Apostolic University, which is found in many countries. There are also ordinary Catholic universities without the word Pontifical.
