Nabu-apla-iddina was a Babylonian king who reigned ca. 888 – 855 BC. His father was King Nabu-shuma-ukin. During much of Nabu-apla-iddina's reign Babylon faced a significant rival in Assyria under the rule of Ashurnasirpal II. Nabu-apla-iddina was able to avoid both outright war and significant loss of territory although there was some low level conflict including a case where he sent a party of troops led by his brother to aid rebels in Sukhu. Later in his reign Nabu-apla-iddina agreed a treaty with Ashurnasirpal II’s successor Shalmaneser III. Internally Nabu-apla-iddina worked on the reconstruction of temples and something of a literary revival took place during his reign with many older works being recopied. He was succeeded by his son Marduk-zakir-shumi I.
