Toros I[1] (hy|Թորոս Ա), also Thoros I,[2] [3] (unknown – 1129[1] / February 17, 1129 – February 16, 1130) was the third lord of Armenian Cilicia[1] (c. 1100[1] / 1102 / 1103 – 1129[1] / 1130).
Toros was the elder son of Constantine I, lord of Armenian Cilicia.
In 1107,[1] encouraged by Tancred, Prince of Antioch, Toros followed the course of the Pyramus River (today the river Ceyhan in Turkey), and seized the strongholds of Anazarbus (a place which had been considered impregnable) and Sis (ancient city).[4] Toros extensively rebuilt the fortifications at both fortresses with tall circuit walls and massive round towers.[5] A beautifully executed dedicatory inscription on the church (dated ca. A.D.1111) records his triumph, and most importantly, traces his Rubenid genealogy.[6] [7]
In 1111, Sultan Malik Shah of Konya entered Armenian territories. Levon saved the Armenian Kingdom of Cilicia into falling in the hands of the Turks.[1]
His death occurred during 1129.[1]
The name of Toros's wife is not known.
