Labarna was also a title of early Hittite rulers,[2] such as Hattusili I.

PU-Sarruma designated Labarna as his successor after his own sons revolted against him.

What little is known about him is culled mainly from the Telepinu Proclamation, which states that he overwhelmed his enemies and "made them borders of the sea",[5] a statement which may refer to conquests as far as the Mediterranean coast in the south, and the Black Sea in the north.

Labarna installed his sons as governors in several cities including Tuwanuwa, Hupisna, Landa, and Lusna (the identities of these cities are uncertain, but thought to perhaps be Tyana, Heraclea Cybistra, Laranda, and Lystra).

Through his conquests, he was responsible for laying the groundwork for the Hittite empire that was to come.
