In the 600s, the spread of Islam wiped the Sassanids off the map, but this was no cause for rejoicing in Ethiopia. The Muslims dealt a severe blow to Ethiopia's Byzantine allies when they took control over most of the Middle East. Many Greek manuscripts were destroyed during this time, and some only survived through Ethiopian translations. Meanwhile, Muslim power ended Ethiopians' dominance over Red Sea trade and cut Ethiopia off from the rest of the christian world.
Gradually the nation's focus shifted away from the Red Sea and toward the Nubian interior. In the centuries that followed, large Muslim populations formed along the Red Sea coast and in southern Ethiopia, and Jewish communities appeared in other areas of the country. Yet christianity remained dominant, and a line of kings who claimed descent from the biblical King Solomon and Queen of Sheba maintained control. christians in southern Muslim lands such as Egypt looked to Ethiopia for leadership, and this in turn may have influenced Europeans' association of the country with the Prester John legend (see box, "Prester John").
