Wollo (Amharic: ወሎ) was a historical province of northern Ethiopia that overlayed part of the present day Amhara, Afar, and Tigray regions. During the Middle Ages this region was known as Bete Amhara and had Amhara kings. Bete Amhara had an illustrious place in Ethiopian political and cultural history. It was the center of the Solomonic Dynasty established by Emperor Yekuno Amlak around Lake Hayq in 1270, the original center of Amhara people, whose territorial reach extended from Lake Hayq and the Beshillo River in the north, the Afar and Argobba lowlands in the east, the Abbay River in the West, and the Awash River just south of modern Addis Ababa.
