Question: Who is the paternal grandfather of Shamash-Shum-Ukin?

Knowledge 1: Shamash-shum-ukin
Shamash-shum-ukin or Shamashshumukin (Akkadian: "Šamaš-šuma-ukin or "Šamaš-šumu-ukīn, meaning "Shamash has established an heir"), also known as Saulmugina and Sarmuge, was the son of the Neo-Assyrian king Esarhaddon and his appointed successor as King of Babylon, ruling Babylonia from 668 BC to his death in 648 BC.Despite being the eldest living son of Esarhaddon at the time, Shamash-shum-ukin was designated as the heir to Babylon in 672 BC and in his stead his younger brother Ashurbanipal was designated as the heir to Assyria.Despite documents from Esarhaddon suggesting that the two brothers were intended to have equal power, Shamash-shum-ukin only ascended to the Babylonian throne months after Ashubanipal had become king and throughout his reign could only make decisions and issue orders if these were also approved and verified by Ashurbanipal.Eventually, Shamash-shum-ukin grew tired of this predicament and in 652 BC he rebelled against his younger brother.Despite successfully raising several allies, a coalition of enemies of Assyria, to his cause, Shamash-shum-ukin's rebellion proved disastrous.After enduring a two-year siege by Ashurbanipal of Babylon, Shamash-shum-ukin committed suicide by burning himself alive. [SEP] Knowledge 2: Esarhaddon
Esarhaddon, also spelled Essarhaddon, Assarhaddon and Ashurhaddon(Akkadian: "Aššur-aḫa-iddina"',meaning "Ashur has given me a brother"'), was the king of the Neo-Assyrian Empire from the death of his father Sennacherib in 681 BC to his own death in 669 BC.The third king of the Sargonid dynasty, Esarhaddon is most famous for his conquest of Egypt in 671 BC' and for his reconstruction of Babylon, which had been destroyed by his father.'After Sennacherib's eldest son and heir Ashur-nadin-shumi had been captured and presumably executed in 694 BC, the new heir had originally been the second eldest son, Arda-Mulissu, but in 684 BC, Esarhaddon, a younger son, was appointed instead.Angered by this decision, Arda-Mulissu and another brother, Sharezer, murdered their father in 681 BC and planned to seize the Assyrian throne.It was only with great difficulty that Esarhaddon successfully ascended to the throne, defeating his brothers in a civil war which lasted six weeks.His brothers’ attempted coup had been unexpected and troublesome for Esarhaddon and he would be plagued by paranoia and mistrust for his officials, governors and male family members until the end of his reign.As a result of this paranoia, most of the palaces used by Esarhaddon were high-security fortifications located outside of the major population centers of the cities.Also perhaps resulting from his mistrust for his male relatives, Esarhaddon's female relatives, such as his mother Naqi'a and his daughter Serua-eterat, were allowed to wield considerably more influence and political power during his reign than women had been allowed in any previous period of Assyrian history.Despite a relatively short and difficult reign, and being plagued by paranoia, depression and constant illness, Esarhaddon remains recognized as one of the greatest and most successful Assyrian kings.He quickly defeated his brothers in 681 BC, completed ambitious and large-scale building projects in both Assyria and Babylonia, successfully campaigned in Media, Arabia, Anatolia, the Caucasus and the Levant, defeated and conquered Egypt and ensured a peaceful transition of power to his two heirs Ashurbanipal and Shamash-shum-ukin after his death.

Ashurbanipal, also spelled Assurbanipal, Asshurbanipal and Asurbanipal( Akkadian:" Aššur- bāni- apli"', meaning" Ashur is the creator of an heir"'), was the king of the Neo-Assyrian Empire from the death of his father Esarhaddon in 669 BC to his own death in 631 BC.The fourth king of the Sargonid dynasty, Ashurbanipal is generally remembered as the last great king of Assyria.At the time of Ashurbanipal's reign, the Neo- Assyrian Empire was the largest empire that the world had ever seen and its capital, Nineveh, was probably the largest city on the planet.Selected as heir by his father in 672 BC despite not being the eldest son, Ashurbanipal ascended to the throne in 669 BC jointly with his elder brother Shamash- shum- ukin, who became king of Babylon.Much of the early years of Ashurbanipal's reign was spent fighting rebellions in Egypt, which had been conquered by his father.The greatest campaigns of Ashurbanipal were those directed towards Elam, an ancient enemy of Assyria, and against Shamash- shum- ukin, who had expected to be an equal to Ashurbanipal and began to resent the overbearing control his younger brother held over him.Elam was defeated in a series of campaigns in 665 BC and 647–646 BC, after which the cities of Elam were destroyed, its people slaughtered and the land was left barren and undefended.Shamash- shum- ukin rebelled in 652 BC and assembled a coalition of Assyria's enemies to fight against Ashurbanipal alongside him but was defeated and committed suicide.Ashurbanipal is most famous for the construction of the Library of Ashurbanipal, the first systematically organized library in the world.The king himself considered the library, a collection of over 30,000 clay tablets with text of a variety of genres including religious documents, handbooks and traditional Mesopotamian stories, as his greatest achievement.Ashurbanipal's library is the primary reason why texts such as the" Epic of Gilgamesh" managed to survive to the present day.
