† 448 - The massacre of Kirkuk
One of the most horrifying massacres occurred in the year 448, in modern day Kirkuk. The King Yasdegerd II began a wave of persecution of Assyrians (and Armenians, in Azerbaijan) throughout Persia. A massacre of ten bishops and 153,000 clergy and laity took place, ". in several consecutive days of slaughter on the mound of Karka d'Bait Sluk (Kirkuk). Local tradition still asserts that the red gravel of the hillock was stained that color by the martyrs' blood, and the martyrium built over the bodies remains to this day." (Introduction to the History of the Assyrian Church, pp. 138). The place where this massacre occurred, to this day, bears the name of the Persian executioner, who was led by the sight of the endurance and faith of the people he was butchering to believe that their faith must truly be from God, and who joined them in their confession, and fate -- Tamasgerd was baptized in his own blood.
