In 746 B.C. Calah joined the rebels, and on the 13th of Iyyar in the following year, Pulu or Pul, who took the name of Tiglath-pileser III., seized the crown and inaugurated a new and vigorous policy.
But the Armenian army was utterly defeated near Malatia on the 12th of Iyyar, and at the end of the day Esar-haddon was saluted by his soldiers as king.
TIGLATH-PILESER or IV., was a successful general who usurped the Assyrian throne on the 13th of Iyyar 745 B.C., after the fall of the older dynasty, and changed his name of Pulu (Pul) to that of the famous conqueror of earlier times.
He had been publicly nominated king of Assyria (on the 12th of Iyyar) by his father Esar-haddon, some time before the latter's death, Babylonia being assigned to his twinbrother Samas-sum-yukin, in the hope of gratifying the national feeling of the Babylonians.
