Hattusili I captured Aleppo

The founding of the Hittite Kingdom is attributed to either Labarna I or Hattusili I (the latter might also have had Labarna as a personal name), who conquered the area south and north of Hattusa. Hattusili I campaigned as far as the Semitic Amorite kingdom of Yamkhad in Syria, where he attacked, but did not capture, its capital of Aleppo. Hattusili I did eventually capture Hattusa and was credited for the foundation of the Hittite Empire.
