Ashurnasirpal II no relation king of Sidon
Chronology
The absolute chronology of the Kings of Sidon from the dynasty of Eshmunazar I has been much discussed in the literature; traditionally placed in the course of the fifth century, inscriptions of this dynasty have been dated back to an earlier period on the basis of numismatic, historical and archaeological evidence. The most complete work addressing the dates of the reigns of these Sidonian kings is by the French historian Josette Elayi who shifted away from the use of biblical chronology. Elayi used all the available documentation of the time and included inscribed Tyrian seals and stamps excavated by the Lebanese archaeologist Maurice Chehab in 1972 from Jal el-Bahr, a neighborhood in the north of Tyre, Phoenician inscriptions discovered by the French archaeologist Maurice Dunand in Sidon in 1965, and the systematic study of Sidonian coins which were the first coins to bear minting dates in antiquity based on the years of reign of the Sidonian kings. Elayi placed the reigns of the descendants of Eshmunazar I between the middle and the end of the sixth century; according to her work Eshmunazar II reigned from c.539 BC until his premature death c.525 BC.Historical context
Sidon, which was a flourishing and independent Phoenician city-state, came under Mesopotamian occupation in the ninth century BC. The Assyrian king Ashurnasirpal II (883–859 BC) conquered the Lebanon mountain range and its coastal cities including Sidon.In 705, the Sidonian king Luli joined forces with the Egyptians and Judah in an unsuccessful rebellion against Assyrian rule, but was forced to flee to Kition with the arrival of the Assyrian army headed by Sennacherib. Sennacherib instated Ittobaal on the throne of Sidon and reimposed the annual tribute. When Abdi-Milkutti ascended to Sidon's throne in 680 BC, he also rebelled against the Assyrians. In response, the Assyrian king Esarhaddon  captured and beheaded Abdi-Milkutti in 677 BC after a three-year siege; Sidon was stripped of its territory, which was awarded to Baal I, the king of rival Tyre and loyal vassal to Esarhaddon.Sidon returned to its former prosperity while Tyre was besieged for 13 years (586–573 BC) by the Chaldean king Nebuchadnezzar II. After the Achaemenid conquest in 529 BC Phoenicia was divided into four vassal kingdoms: Sidon, Tyre, Byblos and Arwad. Eshmunazar I, a priest of Astarte and the founder of his namesake dynasty became king around the time of the Achaemenid conquest of the Levant.  During the first phase of Achaemenid rule Sidon flourished and reclaimed its former standing as Phoenicia's chief city, and the Sidonian kings began an extensive program of mass-scale construction projects attested in the Eshmunazar II sarcophagus and Bodashtart inscriptions.English translation
In the month of Bul, in the fourteenth year of the reign of king Eshmunazar, king of the Sidonians, son of king Tabnit, king of the Sidonians, king Eshmunazar, king of the Sidonians, said as follows: I was carried away before my time, son of a limited number of short days (or: son of a limited number of days I was cut off), an orphan, the son of a widow, and I am lying in this coffin and in this tomb, in a place which I have built. Whoever you are, king or (ordinary) man, may he (sic!) not open this resting-place and may he not search in it after anything because nothing whatsoever has been placed into it. And may he not move the coffin of my resting-place, nor carry me away from this resting-place to another resting-place. Also if men talk to you do not listen to their chatter. For every king and every (ordinary) man, who will open what is above this resting-place, or will lift up the coffin of my resting-place, or will carry me away from this resting-place, may they not have a resting-place with the Rephaïm, may they not be buried in a tomb, and may they not have a son or offspring after them. And may the sacred gods deliver them to a mighty king who will rule them in order to exterminate them, the king or this (ordinary) man who will open what is over this resting-place or will lift up this coffin, and (also) the offspring of this king or of those (ordinary) men. They shall not have root below or fruit above or appearance in the life under the sun. For I who deserve mercy, I was carried away before my time, son of a limited number of short days (or: son of a limited number of days I was cut off), I an orphan, the son of a widow. For I, Eshmunazar, king of the Sidonians, son of king Tabnit, king of the Sidonians, grandson of king Eshmunazar, king of the Sidonians, and my mother Amo[t]astart, priestess of Ashtart, our lady, the queen, daughter of king Eshmunazar, king of the Sidonians, (it is we) who have built the temples of the gods, [the temple of Ashtar]t in Sidon, the land of the sea. And we have placed Ashtart (in) the mighty heavens (or: in Shamem-Addirim?). And it is we who have built a temple for Eshmun, the prince of the sanctuary of the source of Ydll in the mountains, and we have placed him (in) the mighty heavens (or: in Shamem-Addirim?). And it is we who have built temples for the gods of the Sidonians in Sidon, the land of the sea, a temple for Baal of Sidon, and a temple for Ashtart, the Name of Baal. Moreover, the lord of kings gave us Dor and Joppa, the mighty lands of Dagon, which are in the Plain of Sharon, as a reward for the brilliant action I did. And we have annexed them to the boundary of the land, so that they would belong to the Sidonians for ever. Whoever you are, king or (ordinary) man, do not open what is above me and do not uncover what is above me and do not carry me away from this resting-place and do not lift up the coffin of my resting-place. Otherwise, the sacred gods will deliver them and cut off this king and those (ordinary) men and their offspring for ever.
