Umar ibn Abd al-Aziz vs Ur-Nammu

Umar ibn Abd al-Aziz became the eighth Umayyad caliph after the death of Sulayman ibn Abd al-Malik. His reign, though short, was marked by significant reforms and a departure from the policies of his predecessors.

Umar ibn Abd al-Aziz ordered the withdrawal of Umayyad forces from the prolonged and unsuccessful siege of Constantinople. This decision ended a costly military campaign and shifted focus to internal consolidation and reform.

Umar ibn Abd al-Aziz implemented sweeping tax reforms, abolishing the jizya (poll tax) for non-Muslims who converted to Islam and ensuring equal treatment of all subjects. He also ordered the return of confiscated lands and property to their rightful owners.

Ur-Nammu led a military campaign against the Gutian rulers who had dominated Sumer for decades. He defeated them and drove them out of the region, restoring Sumerian independence and establishing his dynasty.

Ur-Nammu overthrew the Gutian rulers and established the Third Dynasty of Ur, reuniting Sumer under a single rule. This marked the beginning of the Ur III period, a time of centralized administration and cultural revival in Mesopotamia.

Ur-Nammu issued the oldest known written legal code, predating Hammurabi's code by three centuries. The code established laws covering property, family, and criminal justice, with penalties including fines and compensation rather than physical punishment.

Ur-Nammu began construction of the Great Ziggurat of Ur, a massive stepped temple dedicated to the moon god Nanna. The project was later completed by his son Shulgi and became one of the most iconic structures of ancient Mesopotamia.
