(Mu-wa-tal-li or Mu-u-at-ta-al-lish) Hittite King, son and successor of Mursilis II. His reign, which we know from the autobiography of his brother and his second successor, called Khattusilis III, was probably started after having eliminated any brother with greater right to the Crown (a text says that "he seized the throne"). In order to avoid problems with his brother Khattusilis (the future Khattusilis III), you had to deliver effective command of high nationwide in replacement of Armadatta and the absolute leadership of the army, giving him at all times proof of loyalty. In addition to his struggles against the gasgas and his own vassal princes (Anatolian and Syrian), his reign was characterized by the constant struggle against Egypt. He was to send an army to deal with the invasion of the Pharaoh Sethi I (19th dynasty) and after waging their own lands of the violent occupation of the gasgas, who had plundered the own Khattushas (Muwattallis had set up its capital in Tarkhuntasha, in the low country), and have signed agreements with some of his vassals (Wilusa, Seha, Aleppo, Kiswadanna), alliances with the akhkhiyawa and even establish marital ties with the Empire of Babylon (Kadashman-Turgu)you were to deal with Egypt. This determination marked his reign, which resulted in the famous hitito-Egypt battle of Kadesh, next to the river Orontes, 1284 b.c. The reason for such battle was, among other factors, the fluctuating policy of their King, the Prince of Amurru Benteshina, who stated a few times prohitita and other proegipcio. This indecisive policy forced the two powers to intervene. In fact, the battle was inconclusive and apparent losses the Pharaoh to Rameses II, as we know from the poem of Pentaur (years later would sign a Treaty of peace and non-aggression between Hatti and Egypt, marked by Rameses II and III Khattusilis). The Hittite troops reached then the own Damascus; Benteshina was deported by Hatti - although it would be then sent to Hakapissa - and treaties with some Syrian Kings (with Talmi-Sharruma of Aleppo, for example) were renewed. After a few facts of weapons against the gasgas to recover Khattushas and a religious process to debug responsibilities about the black magic by Armadatta against Khattusilis and the own Muwattallis, the Hittite King died. The throne passed to his son Urkhi-Teshup, known as Mursilis III, had a wife of second rank.
