Yagbe'u Seyon
Yagbe'u Seyon (throne name Salomon; died 1294) succeeded his father Yekuno Amlak as Ethiopian emperor in June 1285, after years as co-ruler. With his father he had given vestments and utensils to the monastery on Lake Hayq.
He courted his Muslim neighbours and in 1289 wrote to the Mamluk sultan of Egypt over the treatment of Christians, but failed to secure an Abuna from Alexandria.
Marco Polo records that in 1288 the sultan of Aden seized and circumcised an Ethiopian prince's bishop, whereupon the prince captured his capital; some historians identify the prince as Yagbe'u. He crushed a revolt, and when he died in 1294 his sons disputed the throne.
