The vicariate dates from 4 May 1846. The
Capuchin Guglielmo Massaia of the
Latin Church was the first Vicar Apostolic. He was consecrated
Bishop of Cassia on 24 May 1846, and sent on a mission to the Oromo tribes. Only after five years was he able to reach the region of
Galla Assandabo, on 20 November 1852. Having evangelized the districts of
Goudrou,
Lagamara,
Limmou,
Nonna, and
Guera, Massaia entered the
Kingdom of Kaffa on 4 October 1859, where conversions were abundant. He provided the converted tribes with priests, so that when persecution obliged him to flee, Christianity did not disappear. In 1868, Massaia was at
Shewa, where he worked until 1879, and enjoyed the confidence of
Menelik II of Ethiopia, who made him his confidential counsellor. In the interval the missions of Kaffa and Guera were administered by his coadjutor Bishop Felicissimo Coccino, who died 26 February 1878. In 1879 Negus
John of Abyssinia compelled his vassal Menelik to order Bishop Massaia to return to Europe. The bishop had already been banished seven times, and handed over the government of the vicariate to his coadjutor Bishop Taurin Cahagne, from 14 February 1875
titular Bishop of Adramittium. The mission of
Harar was founded by Bishop Taurin, who from 1880 to 1899 worked in this largely Muslim area. He wrote a catechism and works of Christian instruction in the Galla language. The vicariate included the three main districts of Shewa, Kaffa and Harar. ==See also==
