A Babylonian king sets down a long list of case laws, fixing penalties for theft, assault, trade, marriage, and professional failure, and so leaves one of the earliest written attempts to bind a whole society to a single public standard of right.

Core Message
Rather than leave justice to the moment, Hammurabi carves a long roll of rulings into stone where any subject can know them. The Code's first move is to put the standard of right outside the ruler and the judge, so that decisions can be measured against a known rule.
Almost every law follows an if-then shape: a specific act draws a specific consequence. The Code does not preach virtue; it tells you the price of an action, from a multiple of the goods stolen to the loss of a hand or a life.
The same injury costs differently depending on who suffers it. Harm to a gentleman is answered in kind, harm to a poor man in silver, and harm to a slave by a fraction of his price. The Code records a society of ranks, not of equals before the law.
Builders, doctors, boatmen, and herdsmen are held to results. A house that collapses, an operation that kills, a flood let loose through a neglected bank: each carries a named liability. The Code ties a person's trade to the harm it can cause.
Summary
The Code of Hammurabi is a collection of laws set down by a king who ruled Babylonia, over the land between the Tigris and Euphrates, in the early second millennium B.C. In Johns's translation it survives as a sequence of nearly three hundred numbered rulings, each a short statement of a case and the penalty that follows. The introduction explains that the laws were carved on a tall block of black diorite, topped by a carving of the king receiving his laws from the sun-god, and were recovered not in Babylonia but at Susa, where a conqueror had carried the stone away.
The body of the Code reads as a long string of conditions. Most rulings open with 'If a man' and then name an act and its result. The early sections deal with false accusation, witchcraft tested by the river ordeal, theft from temple and palace, and the receiving of stolen goods. A man who cannot prove his charge may die in place of the accused, and a judge who alters a sealed verdict is fined many times over and driven from his seat. The standard is procedural as much as moral: the law cares who can prove what.
Much of the Code governs ordinary economic life. It sets rules for hired fields and orchards, for canals and the floods a careless owner may loose on a neighbour, for loans, deposits, wages, and the price of an ox or a boat. Trade and tenancy are written out in detail because most disputes in this society were about land, grain, silver, and labor. The laws treat property carefully and assign loss to whoever caused it.
Family and rank run through the whole document. There are laws on marriage contracts, dowries, adoption, inheritance, and the standing of wives, children, and slaves. The penalties are openly unequal: an offense against a gentleman, a poor man, or a slave is priced differently, and the famous talion rulings, an eye for an eye and a limb for a limb, apply between equals while the same harm to a lesser person is paid in metal. The Code preserves a layered order and writes that order into its sentences.
What makes the Code matter is less any single law than the fact of the whole. Here a ruler tries to gather the judgments of his age into one fixed, public, written standard, binding professionals to their results and matching consequences to acts. The penalties are harsh and the world unequal, but the underlying ambition, that justice should rest on a known rule rather than on the will of the moment, is one of the oldest and most consequential ideas in the record of human government.
Key Concepts
Nearly every ruling states a specific situation and then the penalty it draws, rather than stating a general principle. The Code teaches by enumerated cases, not by abstract rules.
It shows an early way of making law concrete and predictable: a person could look up the kind of act in question and learn its consequence in advance.
The cost of an offense depends on the social standing of the victim. The same injury is answered in kind for a gentleman, in silver for a poor man, and by a fraction of his value for a slave.
It records, in plain legal terms, a stratified society and shows how law can encode inequality while still claiming to deliver justice.
Builders, doctors, boatmen, and herdsmen answer for the results of their labor. A collapsed house or a fatal operation carries a fixed and serious penalty on the worker.
It is an early form of accountability for competence and safety, tying a trade's rewards to responsibility for the harm it can cause.
Mental Models
Treat a hard situation as a case with a stated condition and a stated consequence, the way each section of the Code does, instead of arguing it from scratch each time.
It turns disputes into lookups against a known rule, making outcomes more predictable and harder to bend to the will of whoever holds power at the moment.
Every wrong in the Code carries a named cost, whether a multiple of the goods, a sum of silver, or a bodily penalty. The act is weighed by what it must repay.
It frames responsibility as a balance to be settled rather than a feeling, clarifying in advance what a given choice will exact.
The Code holds workers to outcomes. The builder whose house falls and kills is punished for the death, regardless of how the work was meant.
It is a stark reminder that in many roles others are protected by consequences, not excuses, and that competence is a duty the law can enforce.
Selected Quotes
If a builder has built a house for a man and has not made strong his work, and the house he built has fallen, and he has caused the death of the owner of the house, that builder shall be put to death.
If a man has caused the loss of a gentleman's eye, his eye one shall cause to be lost.
If he has caused a poor man to lose his eye or shattered a poor man's limb, he shall pay one mina of silver.
