Isin (Sumerian: 𒉌𒋛𒅔𒆠, romanized: I3-si-inki, modern Arabic: Ishan al-Bahriyat) is an archaeological site in Al-Qādisiyyah Governorate, Iraq. Excavations have shown that it was an important city-state in the past.
Ishan al-Bahriyat was visited by Stephen Herbert Langdon for a day to conduct a sounding, while he was excavating at Kish in 1924. Most of the major archaeological work at Isin was accomplished in 11 seasons between 1973 and 1989 by a team of German archaeologists led by Barthel Hrouda. However, as was the case at many sites in Iraq, research was interrupted by the Gulf War (1990-1) and the Iraq War (2003 to 2011). Since the end of excavations, extensive looting is reported to have occurred at the site. Even when the German team began their work, the site had already been heavily looted.
The site of Isin was occupied at least as early as the Early Dynastic period in the middle of the 3rd millennium BC, and possibly as far back as the Ubaid period. While cuneiform tablets from that time were found, the first epigraphic reference to Isin was not until the Ur III period.
When the deteriorating Third Dynasty of Ur (Ur III) finally collapsed at the hands of the Elamites at the end of the third millennium BC, a power vacuum was left that other city-states scrambled to fill. The last king of the Ur Dynasty, Ibbi-Sin, had not the resources nor the organized government needed to expel the Elamite invaders. One of his governmental officials, Ishbi-Erra, relocated from Ur to Isin, another city in the south of Mesopotamia, and established himself as a ruler there. One of Ishbi-Erra's year names reports his defeating Ibbi-Sin in battle.
Although he is not considered part of the Third Dynasty of Ur, Ishbi-Erra did make some attempts at continuing the trappings of that dynasty, most likely to justify his rule. Ishbi-Erra had ill luck expanding his kingdom, however, for other city-states in Mesopotamia rose to power as well. Eshnunna and Ashur were developing into powerful centers. However, he did succeed in repulsing the Elamites from the Ur region. This gave the Isin dynasty control over the culturally significant cities of Ur, Uruk, and the spiritual center of Nippur.
For over 100 years, Isin flourished. Remains of large buildings projects, such as temples, have been excavated. Many royal edicts and law-codes from that period have been discovered. The centralized political structure of Ur-III was largely continued, with Isin's rulers appointing governors and other local officials to carry out their will in the provinces. Lucrative trade routes to the Persian Gulf remained a crucial source of income for Isin.
The exact events surrounding Isin's disintegration as a kingdom are mostly unknown, but some evidence can be pieced together. Documents indicate that access to water sources presented a huge problem for Isin. Isin also endured an internal coup of a sort when Gungunum the royally appointed governor of Larsa and Lagash province, seized the city of Ur. Ur had been the main center of the Gulf trade; thus this move economically crippled Isin. Additionally, Gungunum's two successors Abisare and Sumuel (c. 1905 BC and 1894 BC) both sought to cut Isin off from its canals by rerouting them into Larsa. At some point, Nippur was also lost. Isin would never recover. Around 1860 BC, an outsider named Enlil-bani seized the throne of Isin, ending the hereditary dynasty established by Ishbi-Erra over 150 years earlier. 
Although politically and economically weak, Isin maintained its independence from Larsa for at least another forty years, ultimately succumbing to Larsa's ruler Rim-Sin I.
After the First Dynasty of Babylon rose to power in the early 2nd millennium and captured Larsa, much significant construction occurred at Isin. This ended with a destruction dated to around the 27th year of the reign of Samsu-iluna, son of Hammurabi, based on tablets found there.
Later, the Kassites who took over in Babylon after its sack in 1531 BC, resumed building at Isin. The final significant stage of activity occurred during the Second Dynasty of Isin at the end of the 2nd millennium, most notably by king Adad-apla-iddina.

The city lay on the Isinnitum Canal, part of a set of waterways that connected the cities of Mesopotamia. The patron deity of Isin was Nintinuga (Gula) goddess of healing, and a temple to her was built there. The Isin king Enlil-bani reported building a temple to Gula named E-ni-dub-bi, a temple for Sud named E-dim-gal-an-na, a temple E-ur-gi-ra to Ninisina, as well as a temple for the god Ninbgal.
Ishbi-Erra continued many of the cultic practices that had flourished in the preceding Ur III period. He continued acting out the sacred marriage ritual each year. During this ritual, the king played the part of the mortal Dumuzi, and he had sex with a priestess who represented the goddess of love and war, Inanna (also known as Ishtar). This was thought to strengthen the king's relationship to the gods, which would then bring stability and prosperity on the entire country.
The Isin kings continued also the practice of appointing their daughters official priestesses of the moon god of Ur.
The literature of the period also continued in the line of the Ur III traditions when the Isin dynasty was first begun. For example, the royal hymn, a genre started in the preceding millennium, was continued. Many royal hymns written for the Isin rulers mirrored the themes, structure, and language of the Ur ones. Sometimes the hymns were written in the first person of a king's voice; other times, they were pleas of ordinary citizens meant for the ears of a king (sometimes an already dead one).
It was during this period that the Sumerian King List attained its final form, though it used many much earlier sources. The very compilation of the List seems to lead up to the Isin Dynasty itself, which would give it much legitimacy in the minds of the people because the dynasty would then be linked to earlier (albeit sometimes legendary) kings.
