(Redirected from Turbessel)'Tilbeşar' (Arabic ''Tall Bāshir'', ''Turbessel'' (Frankish)) is a
town in south-eastern
Turkey.
It was a part of the
Byzantine Empire, but came under control of local
Armenian lords in the late 11th century. As a part of the
County of Edessa it was one of the main strongholds of the Frankish counts. After the
fall of Edessa to
Zengi, it became the principal city of what remained of the County until it was eventually sold to the Emperor
Manuel I Comnenus in 1150. It fell to
Nur ed-Din's Muslims within the year.
