Aga of Kish vs Anastasius I

Aga, king of Kish, besieged Uruk, demanding submission from Gilgamesh. The siege was broken by Gilgamesh's forces, and Aga was captured. Gilgamesh spared Aga's life due to a previous favor, ending the conflict between Kish and Uruk.

Aga was the last king of the First Dynasty of Kish, as recorded in the Sumerian King List. After his reign, the kingship passed to Uruk, marking the end of Kish's dominance in Sumer. The exact circumstances of his fall are not recorded.

Anastasius defeated the Isaurian rebels who had opposed his accession. The war ended with the capture and execution of the rebel leaders, and the Isaurians were forcibly resettled, ending their threat to imperial authority.

Emperor Anastasius I abolished the chrysargyron, a highly unpopular tax on trade and commerce that was collected every four years. This reform, along with others, improved the financial stability of the empire and left a substantial surplus in the treasury upon his death.

Anastasius introduced a new system of bronze coinage, including the follis and its fractions. This reform stabilized the currency and facilitated trade, becoming a standard for Byzantine coinage for centuries.

Anastasius ordered the construction of a long defensive wall, the Anastasian Wall, stretching from the Sea of Marmara to the Black Sea. The wall was intended to protect Constantinople from barbarian incursions, but it proved difficult to maintain and was eventually abandoned.
