Sennacherib ( or , meaning "Sîn has replaced the brothers") was the king of the Neo-Assyrian Empire from 705BC until his assassination in 681BC. The second king of the Sargonid dynasty, Sennacherib is one of the most famous Assyrian kings for the role he plays in the Hebrew Bible, which describes his campaign in the Levant. Other events of his reign include his destruction of the city of Babylon in 689BC and his renovation and expansion of the last great Assyrian capital, Nineveh.

Although Sennacherib was one of the most powerful and wide-ranging Assyrian kings, he faced considerable difficulty in controlling Babylonia, which formed the southern portion of his empire. Many of Sennacherib's Babylonian troubles stemmed from the Chaldean tribal chief Marduk-apla-iddina II, who had been Babylon's king until Sennacherib's father defeated him. Shortly after Sennacherib inherited the throne in 705BC, Marduk-apla-iddina retook Babylon and allied with the Elamites. Though Sennacherib reclaimed the south in 700BC, Marduk-apla-iddina continued to trouble him, probably instigating Assyrian vassals in the Levant to rebel, leading to the Levantine War of 701 BC, and himself warring against Bel-ibni, Sennacherib's vassal king in Babylonia.

After the Babylonians and Elamites captured and executed Sennacherib's eldest son Aššur-nādin-šumi, whom Sennacherib had proclaimed as his new vassal king in Babylon, Sennacherib campaigned in both regions, subduing Elam. Because Babylon, well within his own territory, had been the target of most of his military campaigns and had caused the death of his son, he destroyed the city in 689BC.

In the Levantine War, the states in the southern Levant, especially the Kingdom of Judah under King Hezekiah, were not subdued as easily as those in the north. The Assyrians thus invaded Judah. Though the biblical narrative holds that divine intervention by an angel ended the Assyrian siege of Jerusalem by destroying the Assyrian army, an outright defeat is unlikely as Hezekiah submitted to Sennacherib at the end of the campaign. Contemporary records, even those written by Assyria's enemies, do not mention the Assyrians being defeated at Jerusalem. However, the siege remained at least inconclusive, and the Greek historian Herodotus stated that the Assyrians failed in this.

Sennacherib transferred the capital of Assyria to Nineveh, where he had spent most of his time as crown prince. To transform Nineveh into a capital worthy of his empire, he launched one of the most ambitious building projects in ancient history. He expanded the size of the city and constructed great city walls, numerous temples and a royal garden. His most famous work in the city is the Southwest Palace, which Sennacherib named his "Palace without Rival".

After the death of his eldest son and crown prince Aššur-nādin-šumi, Sennacherib originally designated his second son Arda-Mulissu heir. He later replaced him with a younger son, Esarhaddon, in 684BC, for unknown reasons. Sennacherib ignored Arda-Mulissu's repeated appeals to be reinstated as heir, and in 681BC, Arda-Mulissu and his brother Nabu-shar-usur murdered Sennacherib, hoping to seize power for themselves. Babylonia and the Levant welcomed his death as divine punishment, while the Assyrian heartland probably reacted with resentment and horror. Arda-Mulissu's coronation was postponed, and Esarhaddon raised an army and seized Nineveh, installing himself as king as intended by Sennacherib.

Early life

Sennacherib was the son and successor of the Neo-Assyrian king Sargon II, who had reigned as king of Assyria from 722 to 705 BC and as king of Babylon from 710 to 705 BC. The identity of Sennacherib's mother is uncertain. Historically, the most popular view has been that Sennacherib was the son of Sargon's wife Ataliya, although this is now considered unlikely. To have been Sennacherib's mother, Ataliya would have had to be born around the year 760 BC, at the latest, and lived to at least 692 BC, as a "queen mother" is attested in that year, but Ataliya's grave at Nimrud, which was discovered in the 1980s, indicates she was 35 years old at most when she died. The Assyriologist Josette Elayi considers it more plausible Sennacherib's mother was another of Sargon's wives, Ra'īmâ; a stele from Assur (once the capital of Assyria), discovered in 1913, specifically refers to her as the "mother of Sennacherib". Ra'īmâ's existence is a recent discovery, based on a 2014 reading of the inscription on the stele. Sargon claimed he was himself the son of the earlier king Tiglath-Pileser III, but this is uncertain as Sargon usurped the throne from Tiglath-Pileser's other son Shalmaneser V.

Sennacherib was probably born 745 BC in Nimrud. If Sargon was the son of Tiglath-Pileser and not a non-dynastic usurper, Sennacherib would have grown up in the royal palace at Nimrud and spent most of his youth there. Sargon continued to live in Nimrud long after he had become king, leaving the city in 710 BC to reside at Babylon, and later at his new capital, Dur-Sharrukin, in 706 BC. By the time Sargon moved to Babylon, Sennacherib, who served as the crown prince and designated heir, had already left Nimrud, living in a residence at Nineveh. Nineveh had been the designated seat of the Assyrian crown prince since the reign of Tiglath-Pileser. As crown prince, Sennacherib also owned an estate at Tarbiṣu. The royal educator, Hunnî, would have educated Sennacherib and his siblings. They probably received a scribal education, learning arithmetic and how to read and write in Sumerian and Akkadian.

Sennacherib had several brothers and at least one sister. In addition to the older brothers who died before his birth, Sennacherib had a number of younger brothers, some of whom are mentioned as being alive as late as 670 BC, then in the service of Sennacherib's son and successor Esarhaddon. Sennacherib's only known sister, Ahat-abisha, was married off to Ambaris, the king of Tabal, but probably returned to Assyria after Sargon's first successful campaign against Tabal.

Sennacherib's name, Sîn-aḫḫē-erība, means "Sîn (the moon-god) has replaced the brothers" in Akkadian. The name probably derives from Sennacherib not being Sargon's first son, but all his older brothers being dead by the time he was born. In Hebrew, his name was rendered as Snḥryb and in Aramaic it was Šnḥ’ryb. According to a 670 BC document, it was illegal to give the name Sennacherib (then the former king) to a commoner in Assyria, as it was considered sacrilege.

As crown prince

As crown prince, Sennacherib exercised royal power with his father, or alone as a substitute while Sargon was away campaigning. During Sargon's longer absences from the Assyrian heartland, Sennacherib's residence would have served as the center of government in the Neo-Assyrian Empire, with the crown prince taking on significant administrative and political responsibilities. The vast responsibilities entrusted to Sennacherib suggests a certain degree of trust between the king and the crown prince. In reliefs depicting both Sargon and Sennacherib, they are portrayed in discussion, appearing almost as equals. As regent, Sennacherib's primary duty was to maintain relations with Assyrian governors and generals and oversee the empire's vast military intelligence network. Sennacherib oversaw domestic affairs and often informed Sargon of the progress being made on building projects throughout the empire. Sargon also assigned him to the reception and distribution of audience gifts and tribute. After distributing such financial resources, Sennacherib sent letters to his father to inform him of his decisions.

A letter to his father indicates that Sennacherib respected him and that they were on friendly terms. He never disobeyed his father, and his letters indicate he knew Sargon well and wanted to please him. For unknown reasons, Sargon never took him on his military campaigns. Elayi believes that Sennacherib may have resented his father for this as he missed out on the glory attached to military victories. In any event, Sennacherib never took action against Sargon or attempted to usurp the throne despite being more than old enough to become king himself.

Assyria and Babylonia

By the time Sennacherib became king, the Neo-Assyrian Empire had been the dominant power in the Near East for over thirty years, chiefly due to its well-trained and large army, superior to that of any other contemporary kingdom. Though Babylonia to the south had also once been a large kingdom, it was typically weaker than its northern neighbor during this period, due to internal divisions and the lack of a well-organized army. The population of Babylonia was divided into various ethnic groups with different priorities and ideals. Though old native Babylonians ruled most of the cities, such as Kish, Ur, Uruk, Borsippa, Nippur, and Babylon itself, Chaldean tribes led by chieftains who often squabbled with each other dominated most of the southernmost land. The Arameans lived on the fringes of settled land and were notorious for plundering surrounding territories. Because of the infighting of these three major groups, Babylonia often represented an appealing target for Assyrian campaigns. The two kingdoms had competed since the rise of the Middle Assyrian Empire in the 14th century BC, and in the 8th century BC, the Assyrians consistently gained the upper hand. Babylon's internal and external weakness led to its conquest by the Assyrian king Tiglath-Pileser III in 729 BC.

During the expansion of Assyria into a major empire, the Assyrians had conquered various neighboring kingdoms, either annexing them as Assyrian provinces or turning them into vassal states. Because the Assyrians venerated the long history and culture of Babylon, it was preserved as a full kingdom, either ruled by an appointed client king, or by the Assyrian king in a personal union. The relationship between Assyria and Babylonia was similar to the relationship between Greece and Rome in later centuries; much of Assyria's culture, texts and traditions had been imported from the south. Assyria and Babylonia also shared the same language (Akkadian). The relationship between Assyria and Babylon was emotional in a sense; Neo-Assyrian inscriptions implicitly gender the two countries, calling Assyria the metaphorical "husband" and Babylon its "wife". In the words of the Assyriologist Eckart Frahm, "the Assyrians were in love with Babylon, but also wished to dominate her". Though Babylon was respected as the well-spring of civilization, it was expected to remain passive in political matters, something that Assyria's "Babylonian bride" repeatedly refused to be.
