(= Tiglath-phalasar III). King of Assyria (745-727). He brought an end to more than a century of Urartu expansion. He launched a particularly ambitious military campaign that led him to the capital Tushpa, on the shores of Lake Van, to which he laid siege. He radically reorganised the Assyrian empire by transforming former vassal kingdoms into provinces. In 729-728 BCE, he ascended the throne of Babylon, referred to as the reign of Pulu.
