Final answer:
The establishment of the Zagwe Dynasty led to political stability in the region after the Aksumite period's decline. This era was marked by cultural achievements, such as the churches of Lalibela, and the dynasty ruled until overthrown by Yekunno Amlak, initiating the Early Solomonic period.
Step-by-step explanation:
The foundation of the Zagwe Dynasty on a Christianized province some 500 miles to the south of Aksum, eventually led to the return of political stability to the region. Following the fall of Aksum, the rise of the Zagwe Dynasty marked a new period of stability and cultural productivity, as evidenced by the remarkable rock-hewn churches in Lalibela. The Dynasty ruled until it was overthrown in 1270 by Yekunno Amlak who began the Early Solomonic period, a lineage that would not see its conclusion until the 20th century. During the Zagwe period, there was a consolidation of power that provided some degree of stability after a time of decline and internal strife that characterized the end of the Aksumite period.
