Among the lasting benefits assured his subjects was means of getting legal redress. A court of appeals was instituted at Babylon to which any citizen might come to state his wrongs. He codified the laws of the land in 282 laws and inscribed them on monoliths, one of which was found ten years ago in Susa, whither it had been carried by the Elamites about 1100 B.C. In the prologue to the Code he states, "When Marduk sent me to rule the people ... I established law and justice in the land and promoted the welfare of the people." Long after his death his son and successors reaped the benefits of Hammurabi's splendid rule, and the memory of his strength and capacity held the country in check as long as his house endured. Probably for some time before the close of this prosperous era, which came to an end cir. 1700 B.C., mountaineers threatened the eastern borders, and the death of the last king of the dynasty was the occasion for an invasion of the Kassites, a people who emerged from Elam-Media. They seem to have been one of the many bands of mountaineers who gained a livelihood from the products of the mountainous regions and by frequent plundering raids directed against those living on either side of their strongholds. They well knew that Babylon's long devotion to the arts of peace had weakened her military strength, and regarded the time as favorable for winning the fertile valleys for themselves. At all events, they placed their king upon the throne. The inhabitants of southern Babylonia were never possessed of strong patriotism. So long as the land was allowed to rest in peace and the taxes were not increased, there seems to have been no especial interest on the part of the people generally as to who wore the crown. The material development of the country did not suffer long on this occasion, and for nearly 600 years the Kassite dynasty ruled in Babylon. They rapidly took on the culture of their newly acquired state, built temples and directed their attention to the prosperity of the land. As time went on, they wellnigh ceased to be regarded as usurpers. One of their kings set forth his titles thus: "I am Agumkakrime, the son of Tashshigurumash; the illustrious descendant of god Shuqamuna; called by Anu and Bel, Ea and Marduk, Sin and Shamash; the powerful hero of Ishtar, the warrior among the gods. "I am a king of wisdom and prudence; a king who grants hearing and pardon; the son of Tashshigurumash; the descendant of Abiru ... the crafty warrior; the first son of the great Agum; an illustrious, royal scion who holds the reins of the nation (and is) a mighty shepherd.... "I am king of the country of Kashshu and of the Akkadians; king of the wide country of Babylon, who settles the numerous people in Ashnunak; the King of Padan and Alman; the king of Gutium, a foolish nation; (a king) who makes obedient to him the four regions, and a favorite of the great gods."
