Hittites
New Kingdom

With the reign of Tudhaliya I (who may actually not have been the first of that name; see also Tudhaliya), the Hittite Kingdom re-emerged from the fog of obscurity and entered the "Hittite Empire period". Many changes were afoot during this time, not the least of which was a strengthening of the kingship. Settlement of the Hittites progressed in the Empire period. However, the Hittite people tended to settle in the older lands of south Anatolia rather than the lands of the Aegean. As this settlement progressed, treaties were signed with neighboring peoples. During the Hittite Empire period the kingship became hereditary and the king took on a "superhuman aura" and began to be referred to by the Hittite citizens as "My Sun". The kings of the Empire period began acting as a high priest for the whole kingdom – making an annual tour of the Hittite holy cities, conducting festivals and supervising the upkeep of the sanctuaries.

During his reign (c. 1400 BC), King Tudhaliya I, again allied with Kizzuwatna, then vanquished the Hurrian states of Aleppo and Mitanni, and expanded to the west at the expense of Arzawa (a Luwian state).

Another weak phase followed Tudhaliya I, and the Hittites' enemies from all directions were able to advance even to Hattusa and raze it. However, the kingdom recovered its former glory under Šuppiluliuma I (c. 1350 BC), who again conquered Aleppo. Mitanni was reduced to vassalage by the Assyrians under his son-in-law, and he defeated Carchemish, another Amorite city-state. With his own sons placed over all of these new conquests and Babylonia still in the hands of the allied Kassites, this left Šuppiluliuma the supreme power broker in the known world, alongside Assyria and Egypt, and it was not long before Egypt was seeking an alliance by marriage of another of his sons with the widow of Tutankhamen. That son was evidently murdered before reaching his destination, and this alliance was never consummated. However, the Middle Assyrian Empire (1365–1050 BC) once more began to grow in power with the ascension of Ashur-uballit I in 1365 BC. Ashur-uballit I attacked and defeated Mattiwaza the Mitanni king despite attempts by the Hittite king Šuppiluliuma I, now fearful of growing Assyrian power, attempting to preserve his throne with military support. The lands of the Mitanni and Hurrians were duly appropriated by Assyria, enabling it to encroach on Hittite territory in eastern Asia Minor, and Adad-nirari I annexed Carchemish and northeast Syria from the control of the Hittites.

While Šuppiluliuma I reigned, the Hittite Empire was devastated by an epidemic of tularemia. The epidemic afflicted the Hittites for decades and tularemia killed Šuppiluliuma I and his successor, Arnuwanda II. After Šuppiluliuma I's rule, and the brief reign of his eldest son, Arnuwanda II, another son, Mursili II, became king (c. 1330 BC). Having inherited a position of strength in the east, Mursili was able to turn his attention to the west, where he attacked Arzawa. At a point when the Hittites were weakened by the tularemia epidemic, the Arzawans attacked the Hittites, who repelled the attack by sending infected rams to the Arzawans. This was the first recorded use of biological warfare. Mursili also attacked a city known as Millawanda (Miletus), which was under the control of Ahhiyawa. More recent research based on new readings and interpretations of the Hittite texts, as well as of the material evidence for Mycenaean contacts with the Anatolian mainland, came to the conclusion that Ahhiyawa referred to Mycenaean Greece, or at least to a part of it.
