Hammurabi recognized that conquest was of little avail unless followed by the establishment of a just and well-arranged political system, and the inauguration of practical measures to secure the domestic, industrial, and commercial welfare of the people as a whole. He engaged himself greatly, therefore, in developing the natural resources of each particular district. The network of irrigating canals was extended in the homeland so that agriculture might prosper: these canals also promoted trade, for they were utilized for travelling by boat and for the distribution of commodities. As a result of his activities Babylon became not only the administrative, but also the commercial centre of his Empire—the London of Western Asia—and it enjoyed a spell of prosperity which was never surpassed in subsequent times.

There are interesting references to the military successes of his reign in the prologue to the legal Code. It is related that when he “avenged Larsa”, the seat of Rim-Sin, he restored there the temple of the sun god. Other temples were built up at various ancient centres, so that these cultural organizations might contribute to the welfare of the localities over which they held sway. At Nippur he thus
