[20] By c. 738 BC, the Tabalian region, including Tabal proper under the reign of Tuwattīs II,[21] had become a tributary of the Neo-Assyrian king Tiglath-pileser III (r. 745 – 727 BCE), either after his conquest of Arpad over the course of 743 to 740 BC caused the states of the Tabalian region to submit to him, or possibly as a result of a campaign of Tiglath-pileser III there.

[28][29][30] Wasusarmas's Topada inscription also arranged the hieroglyphic signs in which it was written into a royal aedicula, which was the first use of this practice since the Late Bronze Age.

[31] During the century which followed the first attestation of the kingdom of Tabal in 837 BC, it had grown from a small city-state into the largest and strongest of the states of the Tabalian region through aggressive expansionism.

[32] Wasusarmas's continuation of these expansionist ventures brought him into a four year-long[4] conflict with a coalition of eight enemy rulers[22] led by the king of Phrygia that was itself attempting to encroach on the Tabalian region.

Wasusarmas claimed in his inscription at Topada that this Phrygian attack was deflected due to divine intervention, resulting in a victory for the Tabalian coalition.

[28] The deposition of Wasusarmas led to a power vacuum in the Tabalian region, and other local ruler ever claimed the title of "Great King" again after him.

This name, rendered in the inscription as Prizundas (Hieroglyphic Luwian: 𔕸𔖱𔗥𔐭𔔂‎), that is a contracted form of Prizuwandas, itself formed from the term Priz-, which was a cognate of the Ancient Greek stem Phrug-, as found in the ethnonym Phrugia (Φρυγια), of which the Macedonian variant was Brig-, as found in the ethnonym Briges (Βριγες).
