Ethiopia is the only Christian sovereign state that has endured in Africa since the early centuries of Christianity until today.
A tradition traces evangelization of Ethiopia to the Holy Apostles, Matthew and Bartholomew. The birth of official Christianity is due to the consecration by St. Athanasius of Alexandria Bishop Frumentius for Ethiopia. In 330, the Axum empire converted to Christianity.
One of the most famous traditions of the Ethiopian Church is the visit of the Queen of Sheba to King Solomon. The Queen of Sheba, informed of the fame acquired by Solomon, wanted to experience it. She went to Jerusalem near Solomon (I Kings, X, 13). According to the Ethiopian tradition, the Queen of Sheba would have returned pregnant to his kingdom and her son, Menelik I, the first legendary Emperor of Ethiopia, was the son of Solomon. It is even reported that the very young Menelik went to Jerusalem to soak up the wisdom of Solomon before returning to his country.
According to tradition, he brought with him the Ark of the Covenant which nowadays would always be hidden in Ethiopia, Axum.
