Anastasius I vs Sargon of Akkad

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.

Sargon of Akkad conquered the Sumerian city-states, including Uruk and Ur, unifying Mesopotamia under his rule. This marked the creation of the world's first empire, the Akkadian Empire.

Sargon established the city of Akkad as his capital, likely near modern Baghdad. The city became the administrative and cultural center of the Akkadian Empire, though its exact location remains unknown.

Sargon led military campaigns into Anatolia (modern Turkey), reaching the Taurus Mountains and the Mediterranean coast. These expeditions expanded Akkadian influence and secured trade routes for timber and metals.

Sargon faced widespread revolts across his empire in his later years. He suppressed rebellions in Sumer, Elam, and other regions, but the unrest foreshadowed the empire's eventual collapse after his death.
