Queen Ranavalona I (Ranavalona the Cruel) issued a royal edict prohibiting the practice of Christianity in Madagascar, expelled British missionaries from the island, and persecuted Christian converts who would not renounce their religion. People suspected of committing crimes - most went on trial for the crime of practising Christianity - had to drink the poison of the tangena tree. If they survived the ordeal (which few did) the authorities judged them innocent. Malagasy Christians would remember this period as ny tany maizina, or "the time when the land was dark". By some estimates, 150,000 Christians died during the reign of Ranavalona the Cruel. The island grew more isolated, and commerce with other nations came to a standstill. 
In the 11 Northern states of Nigeria that have introduced the Islamic system of law, the Sharia, sectarian clashes between Muslims and Christians have resulted in many deaths, and some churches have been burned. More than 30,000 Christians were displaced from their homes Kano, the largest city in northern Nigeria.
