Code of Hammurabi in the context of Stele

The 2nd millennium BC spanned the years 2000 BC to 1001 BC. In the Ancient Near East, it marks the transition from the Middle to the Late Bronze Age.The Ancient Near Eastern cultures are well within the historical era:The first half of the millennium is dominated by the Middle Kingdom of Egypt and Babylonia. The alphabet develops. At the center of the millennium, a new order emerges with Mycenaean Greek dominance of the Aegean and the rise of the Hittite Empire. The end of the millennium sees the Bronze Age collapse and the transition to the Iron Age.

Other regions of the world are still in the prehistoric period. In Europe, the Beaker culture introduces the Bronze Age, presumably associated with Indo-European expansion. The Indo-Iranian expansion reaches the Iranian plateau and onto the Indian subcontinent (Vedic India), propagating the use of the chariot. Mesoamerica enters the Pre-Classic (Olmec) period. North America is in the late Archaic stage. In Maritime Southeast Asia, the Austronesian expansion reaches Micronesia. In Sub-Saharan Africa, the Bantu expansion begins.

The king of Babylon (Akkadian: šakkanakki Bābili, later also šar Bābili) was the ruler of the ancient Mesopotamian city of Babylon and its kingdom, Babylonia, which existed as an independent realm from the 19th century BC to its fall in the 6th century BC. For the majority of its existence as an independent kingdom, Babylon ruled most of southern Mesopotamia, composed of the ancient regions of Sumer and Akkad. The city experienced two major periods of ascendancy, when Babylonian kings rose to dominate large parts of the Ancient Near East: the First Babylonian Empire (or Old Babylonian Empire, c. 1894/1880–1595 BC) and the Second Babylonian Empire (or Neo-Babylonian Empire, 626–539 BC). Babylon was ruled by Hammurabi, who created the Code of Hammurabi.

Many of Babylon's kings were of foreign origin. Throughout the city's nearly two-thousand year history, it was ruled by kings of native Babylonian (Akkadian), Amorite, Armenian, Kassite, Elamite, Aramean, Assyrian, Chaldean, Persian, Greek and Parthian origin. A king's cultural and ethnic background does not appear to have been important for the Babylonian perception of kingship, the important matter instead being whether the king was capable of executing the duties traditionally ascribed to the Babylonian king: establishing peace and security, upholding justice, honouring civil rights, refraining from unlawful taxation, respecting religious traditions, constructing temples, providing gifts to the gods in the temples and maintaining cultic order. Babylonian revolts of independence during the times the city was ruled by foreign empires probably had little to do with the rulers of these empires not being Babylonians and more to do with the rulers rarely visiting Babylon and failing to partake in the city's rituals and traditions.

Hammurabi (/ˌhæmʊˈrɑːbi/; Old Babylonian Akkadian: 𒄩𒄠𒈬𒊏𒁉, romanized: Ḫammu-rāpi; Akkadian: [xammuˈraːpʰi]; c. 1810 – c. 1750 BC), also spelled Hammurapi, was the sixth Amorite king of the Old Babylonian Empire, reigning from c. 1792 to c. 1750 BC. He was preceded by his father, Sin-Muballit, who abdicated due to failing health. During his reign, he conquered the city-states of Larsa, Eshnunna, and Mari. He ousted Ishme-Dagan I, the king of Assyria, and forced his son Mut-Ashkur to pay tribute, bringing almost all of Mesopotamia under Babylonian rule.

Hammurabi is best known for having issued his eponymous code, which he claimed to have received from Shamash, the Babylonian god of justice. Unlike earlier Sumerian law codes, such as the Code of Ur-Nammu, which had focused on compensating the victim of the crime, the Law of Hammurabi was one of the first law codes to place greater emphasis on the physical punishment of the perpetrator. It prescribed specific penalties for each crime and is among the first codes to establish the presumption of innocence. They were intended to limit what a wronged person was permitted to do in retribution. The Code of Hammurabi and the Law of Moses in the Torah contain numerous similarities.

Criminal investigation is an applied science that involves the study of facts that are then used to inform criminal trials. A complete criminal investigation can include searching, interviews, interrogations, evidence collection and preservation, and various methods of investigation. Modern-day criminal investigations commonly employ many modern scientific techniques known collectively as forensic science.

Criminal investigation is an ancient science that may have roots as far back as c. 1700 BCE in the writings of the Code of Hammurabi. In the code, it is suggested that both the accuser and the accused had the right to present evidence they collected. In the modern era, criminals investigations are most often done by government police forces. Private investigators are also commonly hired to complete or assist in criminal investigations.

The history of slavery spans many different cultures, nationalities, and religions from ancient times to the present day. Likewise, its victims have come from many different ethnicities and religious groups. The social, economic, and legal positions of slaves have differed vastly in different systems of slavery in different times and places.Slavery has been found in some hunter-gatherer populations, particularly as hereditary slavery, but the conditions of agriculture with increasing social and economic complexity offer greater opportunity for mass chattel slavery. Slavery was institutionalized by the time the first civilizations emerged (such as Sumer in Mesopotamia, which dates back as far as 4000 BC). Slavery features in the Mesopotamian Code of Hammurabi (c. 1750 BC), which refers to it as an established institution.Slavery was widespread in the ancient world in Europe, Asia, the Middle East, Africa, and the Americas.

Slavery became less common throughout Europe during the Early Middle Ages but continued to be practiced in some areas. Both Christians and Muslims captured and enslaved each other during centuries of warfare in the Mediterranean and Europe. Islamic slavery encompassed mainly Western and Central Asia, Northern and Eastern Africa, India, and Europe from the 7th to the 20th century. Islamic law approved of enslavement of non-Muslims, and slaves were trafficked from non-Muslim lands: from the North via the Balkan slave trade and the Crimean slave trade; from the East via the Bukhara slave trade; from the West via Andalusian slave trade; and from the South via the Trans-Saharan slave trade, the Red Sea slave trade and the Indian Ocean slave trade.

Hugo Winckler (4 July 1863 – 19 April 1913) was a German orientalist, archaeologist, and historian who uncovered the capital of the Hittite Empire (Hattusa) at Boğazkale, Turkey.

A student of the languages of the ancient Middle East, he wrote extensively on Assyrian cuneiform and the Old Testament, compiled a history of Babylonia and Assyria that was published in 1891, and translated both the Code of Hammurabi and the Amarna letters. In 1904, he was appointed professor of Oriental languages at the University of Berlin.

The Hittite laws, also known as the Code of the Nesilim, constitute an ancient legal code dating from c. 1650 – 1500 BCE. They have been preserved on a number of Hittite cuneiform tablets found at Hattusa (CTH 291–292, listing 200 laws). Copies have been found written in Old Hittite as well as in Middle and Late Hittite, indicating that they had validity throughout the duration of the Hittite Empire (ca. 1650–1100 BCE).

The Hittite laws reflected the empire's social structure, sense of justice, and morality, addressing common outlawed actions such as assault, theft, murder, witchcraft, and divorce, among others. The code is particularly notable due to a number of its provisions, covering social issues that included the humane treatment of slaves. Although they were considered lesser than free men, the slaves under the code were allowed to choose whomever they wanted to marry, buy property, open businesses, and purchase their freedom. In comparison with the Code of Hammurabi or the Middle Assyrian Laws, the Code of Nesilim also provided less-severe punishments for the code's violations.

Retributive justice is a legal concept whereby the criminal offender receives punitive damages proportional or similar to the crime. As opposed to revenge, retribution—and thus retributive justice—is not personal, is directed only at wrongdoing, has inherent limits, involves no pleasure at the suffering of others (e.g., schadenfreude, sadism), and employs procedural standards. Retributive justice contrasts with other purposes of punishment such as deterrence (prevention of future crimes), exile (prevention of opportunity) and rehabilitation of the offender.

The concept is found in most world cultures and in many ancient texts. Classical texts advocating the retributive view include Cicero's De Legibus (1st century BC), Immanuel Kant's Science of Right (1790), and Georg Wilhelm Friedrich Hegel's Elements of the Philosophy of Right (1821). The presence of retributive justice in ancient Jewish culture is shown by its mention in the law of Moses, which refers to the punishments of "life for life, eye for eye, tooth for tooth, hand for hand, foot for foot" as also attested in the Code of Hammurabi. Documents assert similar values in other cultures, though the judgment of whether a particular punishment is appropriately severe can vary greatly across cultures and individuals in accord with circumstance.

Father Jean-Vincent Scheil (born 10 June 1858, Kœnigsmacker – died 21 September 1940, Paris) was a French Dominican scholar and Assyriologist. He is credited as the discoverer of the Code of Hammurabi in Persia. In 1911 he came into possession of the Scheil dynastic tablet and first translated it.After being ordained in 1887, he took courses in Egyptology and Assyriology at the École des Hautes Études, and was a student at the Collège de France, where he was a pupil of Assyriologist Julius Oppert. In 1890/91 as a member of the French Archaeological Mission of Cairo, he took part in excavations at Thebes. In 1892 he conducted excavations near Baghdad for the Ottoman Imperial Museum, followed by work in Constantinople, where he was tasked with classifying and drafting a catalog of Assyrian, Chaldean and Egyptian antiquities of the museum.

In 1895 he became a lecturer at the École Pratique des Hautes Études, where in 1908 he was named its director. In 1908 he also became a member of the Académie des Inscriptions et Belles-Lettres. In 1923 he became an officer of the Légion d'honneur.

"An eye for an eye" (Biblical Hebrew: עַיִן תַּחַת עַיִן, ʿayīn taḥaṯ ʿayīn) is a commandment found in the Book of Exodus 21:23–27 expressing the principle of reciprocal justice measure for measure. The earliest known use of the principle appears in the Code of Hammurabi, which predates the writing of the Hebrew Bible but not necessarily oral traditions.

The law of exact retaliation (Latin: lex talionis), or reciprocal justice, bears the same principle that a person who has injured another person is to be penalized to a similar degree by the injured party. In softer interpretations, it means the victim receives the estimated value of the injury in compensation. The intent behind the principle was to restrict compensation to the value of the loss.

The legal code was a common feature of the legal systems of the ancient Middle East. Many of them are examples of cuneiform law. The oldest evidence of a code of law was found at Ebla, in modern Syria (c. 2400 BC). The Sumerian Code of Ur-Nammu (c. 2100–2050 BC), then the Babylonian Code of Hammurabi (c. 1760 BC), are amongst the earliest originating in the Fertile Crescent. In the Roman empire, a number of codifications were developed, such as the Twelve Tables of Roman law (first compiled in 450 BC) and the Corpus Juris Civilis of Justinian, also known as the Justinian Code (429–534 AD). In India, the Edicts of Ashoka (269–236 BC) were followed by the Law of Manu (200 BC). In ancient China, the first comprehensive criminal code was the Tang Code, created in 624 AD in the Tang Dynasty.
