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. According to "The Edict of Telepinu", dating to the 16th century BC, "Hattusili was king, and his sons, brothers, in-laws, family members, and troops were all united. Wherever he went on campaign he controlled the enemy land with force. He destroyed the lands one after the other, took away their power, and made them the borders of the sea. When he came back from campaign, however, each of his sons went somewhere to a country, and in his hand the great cities prospered. But, when later the princes' servants became corrupt, they began to devour the properties, conspired constantly against their masters, and began to shed their blood." This excerpt from the edict is supposed to illustrate the unification, growth, and prosperity of the Hittites under his rule. It also illustrates the corruption of "the princes", believed to be his sons. The lack of sources leads to uncertainty of how the corruption was addressed. On Hattusili I's deathbed, he chose his grandson, Mursili I (or Murshilish I), as his heir.
