Halal butchery practices became common when Islam spread through Ethiopia as vibrant communities developed because of the import and export of products around the Red Sea, and to Egypt, India, and the Arabian Peninsula, archaeologists have found.
New excavations at three sites in the east of the country completed by the University of Exeter and the Ethiopian Authority for Research and Conservation of Cultural Heritage have uncovered around 50,000 animal bones dating from the eighth/ninth centuries onwards, and showing people living there at this early time ate a Muslim diet 400 years before major Mosques or burial sites were built in the 12th century.
