Enforcing agricultural reforms.
Under Hammurabi’s rule, a series of large-scale public works, particularly the construction of irrigation projects, were essential in improving the agricultural productivity of the empire. This initiative helped increase the stability and prosperity of the Babylonian economy. The Code of Hammurabi, which established clear laws, also contributed to economic improvement by providing a stable and predictable legal environment for trade and commerce.
