[3] Sangara likely accessed the throne of Carchemish only a short time after king Katuwa known from Hieroglyphic Luwian sources.
[4] Prior to a discovery of new evidence in 2015,[3] he was only mentioned in texts of the Assyrian kings Ashurnasirpal II and Shalmaneser III.
Facing the Assyrian army Sangara capitulated quickly and paid a rich tribute because Carchemish was one of the wealthiest Syro-Hittite states of that time.
[9] In 858 BC Sangara participated in an anti-Assyrian coalition against Shalmaneser III which was formed by Aḫuni of Bit Adini, Hayyanu of Sam'al, Šuppiluliuma of Pattin and himself.
For the period after 848 BC nothing more is known about Sangara but it is likely stayed on his throne as a faithful vassal of the Assyrian king as his ally Hadram of Bit Agusi did.
