A palace revolution overthrew the Negus, and heresy again assumed the reigns of power. From then until the middle of the nineteenth century, a silence as of death lay on the Church of Abyssinia. In 1846, the Holy See divided Ethiopia into two Apostolic vicariates: that of Abyssinia, trusted to the Lazarists, and that of Galla, given to the Capuchins. In the former, the labors and successes of M. de Jacobus awakened the jealousy of the schismatic clergy.
An ex-Emir of Cairo, who had become Abouna of Ethiopia, and a man of low birth named Kassa, who had been anointed Negus under the name of Theodoros, joined forces to persecute the Catholics, drive out the missionaries, and put them to death. The Negus Johannes IV, who succeeded Theodoros, followed in his predecessor's footsteps. His reign of twenty years was a time of trouble and suffering for the Catholics of Abyssinia".
