PU-Sarruma (PU-LUGAL-ma, mPU-Šàr-(rù)-ma, possibly representing Hišmi-Šarruma) is a conjectured pre-Empire king of the Hittites.
The conjecture was forwarded by Emil Forrer and is not commonly accepted.
[2] Virtually nothing is known of PU-Šarruma's life, who is a very shadowy figure.
PU-Šarruma's sons had turned against their father, so that, while he was in the city of Šanahwitta, he named his son-in-law Labarna as his successor.
[3] However, Papahdilmah still had support among the king's servants and chief officers.
