Question: Parattarna was the name of a Hurrian king of Mitanni in the fifteenth century BC who disposed of what king of Alalakh?
Context: Kirta is a legendary Hurrian king.  He is thought to have founded the dynasty of Mitanni, but no contemporary inscriptions from his time are known to exist.  He may have lived around 1500 BC. Idrimi was the king of Alalakh in the 15th century BC (c. 1460–1400 BC).  He was a Hurrianised son of Ilim-Ilimma I the king of Halab, now Aleppo, who had possibly been deposed by the new regional master, Barattarna or Parshatatar, king of the Mitanni.  Nevertheless, he succeeded in gaining the throne of Alalakh with the assistance of a group known as the "Habiru".  Idrimi founded the kingdom of Mukish and ruled from Alalakh as a vassal to the Mitanni state.  He also invaded the Hittite territories to the north, resulting in a treaty with the country Kizzuwatna.  Idrimi is known from an inscription on a statue found at Alalakh by Leonard Woolley in the 1930s and 1940s, revealing new insights about the history of Syria in the mid-second millennium. Yamhad was an ancient Semitic kingdom centered on Ḥalab (Aleppo), Syria.  The kingdom emerged at the end of the 19th century BC, and was ruled by the Yamhadite dynasty kings, who counted on both military and diplomacy to expand their realm.  From the beginning of its establishment, the kingdom withstood the aggressions of its neighbors Mari, Qatna and Assyria, and was turned into the most powerful Syrian kingdom of its era through the actions of its king Yarim-Lim I.  By the middle of the 18th century BC, most of Syria minus the south came under the authority of Yamhad, either as a direct possession or through vassalage, and for nearly a century and a half, Yamhad dominated northern, northwestern and eastern Syria, and had influence over small kingdoms in Mesopotamia at the borders of Elam.  The kingdom was eventually destroyed by the Hittites, then annexed by Mitanni in the 16th century BC. Artatama II (Sanskrit: "Ṛta-dhaman", "his abode is "Ṛta"") was a usurper to the throne of king Tushratta of Mitanni in the fourteenth century BC.  He may have been a brother of Tushratta or belonged to a rival line of the royal house.  The Hittite king Suppiluliuma I made a treaty with Artatama following his invasion of Mitanni.  His son, Shuttarna III, ruled Mitanni after him. The Hurrian language was spoken by the Hurrians (Khurrites), a people who entered northern Mesopotamia around 2300 BC and had mostly vanished by 1000 BC.  Hurrian was the language of the Mitanni kingdom in northern Mesopotamia, and was likely spoken at least initially in Hurrian settlements in Syria.  It is generally believed that the speakers of this language originally came from the Armenian Highlands and spread over southeast Anatolia and northern Mesopotamia at the beginning of the 2nd millennium BC. Artatama I (Sanskrit: "Ṛta-dhaman", "his abode is "Ṛta"") was a king of the Hurrian kingdom of Mitanni in the late fifteenth century BC.  His reign coincided with the reigns of Egyptian pharaohs Amenhotep II and Thutmose IV. Shaushtatar (also spelled Šauštatar) was a king of the Hurrian kingdom of Mitanni in the fifteenth century BC. Pilliya was a king of Kizzuwatna ca.  the 15th century BC (short chronology).  He signed a treaty with Idrimi of Alalakh, allying with the Mitanni empire. Shuttarna I was an early king of the Mitanni.  His name is recorded on a seal found at Alalakh.  The inscription reads "son of Kirta" and is the only reference about this king yet discovered.  He would have reigned in the early 15th century BC. Parshatatar, Paršatar, Barattarna, or Parattarna was the name of a Hurrian king of Mitanni in the fifteenth century BC.  Very few records of him are known as sources from Mitanni are rare.  Most information we have about the kingdom, especially its early history and kings come from records outside of the state.  Dates for the kings can be deduced by comparing the chronology of Mitanni and other states, especially ancient Egypt, at a later date and working back the figures.  Information is found in the biography of Idrimi of Alalakh (or Alalah, which became the capital of Aleppo).  Parshatatar conquered the area and made Idrimi his vassal, Idrimi becoming king of Aleppo.  Mitanni in his time probably extended as far as Arrapha in the east, Terqa in the south, and Kizzuwatna in the West.  Parshatatar may have been the Mitannian king the Egyptian Pharaoh Thutmosis I met at the Euphrates River in a campaign early in his reign (around 1493).  Information about his death is mentioned in a record from Nuzi dated to the death of king Parshatatar, possibly around 1420.
