Neo-Assyrian Empire
A civil war then began in 828 BC as his eldest son Ashur-nadin-aplu and 27 cities rebelled against the governors of Assyria, allowing Babylonia, the Medes, Manneans, Arameans, Neo-Hittites, and Persians to largely recapture their land and Urartu to exert its influence in the region. Second son of Ashurnasirpal Shamshi-Adad V finally ended the Civil War in 824 BC, the same year as his father's death, and spent almost the entire rest of his reign trying to re-conquer lost land before his death in 811 BC, when succeeded by his wife, Queen Sammuramat and then his son Adad-nirari III in 806 BC.
