The factor that led to the emergence of the Zagwe dynasty was the decline of the Aksumite Empire. The Aksumite Empire, which was a powerful kingdom in ancient Ethiopia, began to decline in the 9th century due to various factors such as economic decline, political instability, and the rise of Islamic powers in the region. As a result, the Zagwe dynasty, which was a local ruling family in the region of Lasta, was able to seize power and establish their own dynasty. They ruled from the 10th to the 13th century, with their capital at Roha (now known as Lalibela).
