Origins and conquest of Babylonia and
Middle Assyrian Empire kings In 1595 BC,
Samsi-Ditana, king of
Babylon, was defeated by
Mursili I, king of the
Hittites, who seized the statue of
Marduk kept in the
Esagila, the great temple of the city of Babylon, which he took with him. This defeat marked the end of the
Babylonian Amorite dynasty, already greatly weakened by the various rivals, among them the Kassites. According to the Babylonian royal list, Agum II would have taken over Babylon after the city was sacked by the Hittites. According to the same source,
Agum II would have been the tenth sovereign of the dynasty of the Kassite kings (founded by a certain
Gandas), who would have reigned who knows where during the second half of the 18th century BC. Possibly the Kassites were allied with the Hittites and supported their campaign to seize power. There are no mentions of the exact origin of the kassites in ancient texts. The first mention of them dates from the 18th century BC in
Babylon, but they are also mentioned in
Syria and
Upper Mesopotamia in the following centuries. However, most experts place their origin in the
Zagros mountain range, where Kassites were still found during the first half of the first millennium BC. The first Kassite sovereign attested as king of Babylon seems to be
Burna-Buriash I. This dynasty had as its rival that of the Sea Country, located south of Babylon around the cities of
Uruk,
Ur and
Larsa, which was defeated in the early 15th century BC by the Kassite sovereigns
Ulamburiash and Agum III. After this military victory, Babylon's preponderance in southern Mesopotamia was not challenged again and the Kassite sovereigns dominated the entire territories of Sumer and Akkadia, which became the country of
Karduniash (
Karduniaš; the term Kassite equivalent to Babylon), which was one of the great powers of the Middle East. The only notable territorial gain made by Kassite rulers thereafter was the island of
Bahrain, then called
Dilmum, where a seal bearing the name of a Babylonian governor of the island was discovered, although nothing is known about the duration of this rule.
Diplomatic relations , first half of the 14th century BC. The 14th and 13th centuries BC marked the heyday of Babylon's Kassite dynasty. Its kings equaled their contemporary great sovereigns of
Egypt,
Hati,
Mitanni and
Assyria, with whom they maintained diplomatic relations, in which they have the privilege of bearing the title of "great king" (
šarru rabû), which involved abundant correspondence and exchanges of gifts (
šulmānu). This system, attested mainly by the
Amarna letters in Egypt and of
Hatusa (the Hittite capital), was ensured by emissaries called
mār šipri, involved important exchanges of luxury goods, which included much
gold and other
precious metals, in a scheme of gifts and contradons, more or less respected by some sovereigns, which sometimes took place with some minor tensions. These exchanges were made as gifts of friendship or homage when a king was enthroned. The diplomatic language was Babylonian
Akkadian, in the so-called "Middle Babylonian" form, as was the case in the preceding period. The courts of the regional powers of this period connected through dynastic marriages, and the Kassite kings took an active part in this process, establishing multi-generational ties with some courts, such as that of the Hittites (which possibly lay behind their seizure of power in the city of Babylon) and the
Elamites.
Burna-buriash II (ca. 1359-1333 BC) married one of his daughters to the
pharaoh Akhenaten (3rd quarter of the 14th century BC) and another to the Hittite king
Suppiluliuma II, while he himself espoused the daughter of the Assyrian king
Ashur-uballit I. There were also Babylonian princesses who married Elamite sovereigns. These practices were intended to strengthen the ties between the different royal houses, which in the last two cases were direct neighbors, in order to avoid political tensions. With more distant partners, such as the Hittites, they were essentially a form of prestige and influence, since the Babylonian princesses and the specialists (doctors and scribes) who were sent to the Hittite court were protagonists of Babylonian cultural influences in the Hittite kingdom.
Conflicts with Assyria and Elam and
Middle Assyrian Empire Babylon became involved in a series of conflicts with Assyria when Assyrian ruler
Ashur-uballit I broke free from
Mitanni rule in 1365 BC, which marked the beginning of a multi-secular confrontation between northern and southern
Mesopotamia.
Burna-Buriash II (r. ca. 1359-1333 BC) initially took a dim view of Assyrian independence, as he considered this region one of his vassals, but eventually married the daughter of the Assyrian king, with whom he had a son, Kara-hardash. The latter ascended the throne in 1333 BC, but was assassinated shortly thereafter and was succeeded by Nazi-Bugash. Ashur-uballit reacted to his grandson's murder and invaded Babylon to put his other grandson,
Kurigalzu II (r. 1332-1308 BC) on the throne. The latter kept his allegiance to his grandfather until he died, but provoked the next Assyrian king Enlil-nirari, which led to a series of conflicts that lasted for over a century and culminated in the confrontation between
Kashtiliash IV (r. 1232-1225 BC) of Babylon and
Tukulti-Ninurta I (r. ca. 1243-1207 BC) of Assyria. The latter invaded and devastated Babylon, sacking the capital, from where he deported thousands of people. The situation then became increasingly confused, as the Assyrians failed to establish a lasting domination in Babylon, despite the will of Tukulti-Ninurta, who had his victory described in a long epic text (the Epic of Tukulti-Ninurta) and proclaimed himself king of Babylon. The conflicts continued and escalated when the Elamite king
Kidin-Hutran (r. 1245-1215 BC) became involved, possibly in solidarity with the Kassite kings, to whom he was linked by marriage. Kidin-Hutran devastated Nippur and made the situation difficult for the Assyrian-imposed rulers in Babylon, who were deposed one after another until 1217 BC. After the assassination of
Tukulti-Ninurta in 1208 BC and the internal turmoil that followed in Assyria, the kings of Babylon were able to regain their autonomy, to the extent that it was the Babylonian king
Merodach-Baladan I (r. 1171-1159 BC) who helped the Assyrian king Ninurta-apil-Ecur take power in the northern kingdom, before the latter turned against him unsuccessfully. Shortly after the end of these conflicts, the Elamite armies entered Mesopotamia, commanded by their king
Shutruk-Nakhunte (r. 1185-1160 BC), at a time when Babylon and Assyria were weakened by recent warfare. The Elamite king's intervention in Babylon may have been motivated by his desire to assert his rights to the Babylonian throne resulting from his family ties to the Kassite dynasty, at a time when succession disputes had weakened the legitimacy of the Babylonian sovereigns.
Fall of the dynasty In 1160 BC, at a time when Merodach-Baladan had managed to stabilize power in Babylon, the Elamite monarch
Shutruk-Nakhunte invaded Babylon and sacked its major cities. It was during this period that several major monuments of Mesopotamian history were taken to Susa, the Elamite capital. Among the looted pieces were several statues and
stelae, such as that of the victory of
Naram-Sim of Akkad or the
Code of Hammurabi, as well as other stelae from various eras, including kassite kudurrus. After several years of resistance led by Kassite sovereigns, the next Elamite king, Kutir-Nacunte III, dealt the coup de grace to the Kassite dynasty in 1155 BC and took the statue of the god
Marduk to
Elam as a symbol of Babylon's submission. == Institutions of the Kassite kingdom ==
