Starting in the Old Assyrian Period, the Assyrian king chose a limmu (aka eponymous magistrate) for each year. This distributed authority, allowing the limmu to perform certain cultic acts. Records listing each year and its limmu are critical for reconstructing Assyrian chronology. The limmuship rotated amidst Assyrian noble families and sometimes even the king himself. and in which king participated. The limmu tradition continued through the period of decline (~1,050-934 BC) separating the Middle and the Neo-Assyrian Period; only limmuships from ~892-~648 BC have been reconstructed.
