Who is known as the 6th king of the 1st Babylonian Dynasty, famous for establishing a code of laws?

The sixth king of the first Babylonian Dynasty, renowned for establishing a comprehensive code of laws, is Hammurabi. His most notable achievement, the Code of Hammurabi, is one of the earliest and most complete written legal codes in history, created around 1754 BC. This code consists of 282 laws governing a wide range of civil, criminal, and commercial issues, reflecting the values and social structure of Babylonian society at the time. Hammurabi's influence on law and governance has had a lasting impact on legal systems in various cultures throughout history, emphasizing justice and accountability.

Other figures listed, such as Nebuchadnezzar and Sargon, are also significant in their own right but are associated with different periods and achievements in Mesopotamian history. Nebuchadnezzar is often remembered for his monumental building projects and military conquests in the Neo-Babylonian Empire, while Sargon is recognized as a prominent leader who established the Akkadian Empire, predating Hammurabi. The term "Heresy" does not refer to a king or legal figure and thus is unrelated to the question.
