Shamsi-Adad I, of Amorite origin, was a capable administrator who monitored all aspects of his kingdom. Like many ancient Mesopotamia kings, he engaged in an extensive building program, and his reign is especially known for the construction of canal and irrigation systems.
Pressure from the Babylonians under Hammurabi and from the expanding Hittite Empire to the west was followed by four centuries of foreign domination.
Around 1808 BC, Shamsi-Adad I invaded and conquered the city state of Ashur, the ancient capital of Assyria. Shamsi-Adad continued to expand his kingdom by seizing land from Mari and Babylon and by taking control of important attitude routes in Syria and Anatolia.
At the peak of their power the Assyrians controlled an empire that encompassed present-day Iraq, Syria, Jordan, Israel and Egypt, as well as large parts of Turkey and Iran.
