Due to the proximity of Somalis to the
Axumite and Southern Arabian Cultures, early Christianity and Judaism was professed by some in the region of Somalia as can be seen by inscriptions, gravesites with stone crosses, and codices in the
Geʽez script. However, the advent of Islam in the region saw an end to Christianity, not making a return until Italian colonization. In 1903, the first Christian missionaries under the Trinitarian Fathers arrived in Somalia. According to Listowel, they started by providing education and assistance to the poor and sick in the country, with Fr. Jelib founding a
leper colony at the mouth of the
Jubba River, housing between 350 and 400 afflicted. Still however at the time of publishing of the
Catholic Encyclopedia in 1913, there were virtually no Christians observed in the Somali territories, outside of the around 100–200 followers which existed in the schools and
orphanages across the few Catholic
missions run by the English, French, and Italians. No Catholic missions are known to have existed in
Italian Somaliland during the same period. In 1928, a Catholic cathedral was built in Mogadishu by order of
Cesare Maria De Vecchi, a Catholic governor of "Somalia italiana" who promoted the "Missionari della Consolata" Christianization of Somali people. Upon the completion of the cathedral, it stood as the largest in
East Africa The Bishop of Mogadishu, Venanzio Francesco Filippini, OFM, declared in 1940 that there were about 40,000 Somali Catholics due to the work of missionaries in the rural regions of Juba and Shebelle, but
World War II damaged in an irreversible way most of the Catholic missions in
Italian Somalia. Most were Somali Bantu. The
Bible was first translated into Somali only in 1979. The Diocese of Mogadishu estimates that there were about 100 official
Roman Catholic practitioners in Somalia in 2004. This was down from a high of 8,500 adherents at the start of the
trusteeship period in 1950, under the Prefecture Apostolic of Benadir of the Vicariate Apostolic of Mogadiscio. Somalia is included in the Episcopal Area of the Horn of Africa of the
Anglican Diocese of Egypt, though there are no current local congregations. The
Adventist Mission indicates that there are no Adventist members in Somalia, and that
Christianity in general has seen little growth there. In August 2025,
International Christian Concern reported that a video posted on
TikTok by a Somali about one of its articles went viral, with many people posting extremely violent comments. ==Persecution==
