[3] Tegulet, the ancient residence of the Ethiopian and Shewan rulers, is believed to lie in this woreda.

[4] Tegulet first served as center of the Sultanate of Showa, with its capital of "Siyon" (Zion, also known as "Marade"[5]) located in the area.

[7] Wedem Arad later made it the center of his kingdom after Showa's fall[8][9][10][11] and Debre Birhan would be founded by Zara Yaqob nearby, serving as the base of him and his descendants, the later Meridazmatches.

The majority of the inhabitants practiced Ethiopian Orthodox Christianity, with 97.43% reporting that as their religion, while 2.37% of the population said they were Muslim.
