How Ancient Legal Documents Made Modern Law We Know Today


How Ancient Legal Documents Made Modern Law We Know Today

We are all familiar with the basic principles of our legal system and how they became enshrined in law over generations. You might even know how laws are passed in the United States. But what about laws before America? How did ancient legal documents written thousands of years ago influence modern law?

Looking Back Through Time

We need to look back in time to understand how we got here. Let's examine some of the greatest legal documents ever written and how they established certain legal principles we still hold today.

Hammurabi's Code

One of the earliest precursors to modern law was the Code of Hammurabi. Written in Ancient Mesopotamia nearly 3,800 years ago by the Babylonian King Hammurabi, the Code was a collection of 282 laws.

Who Was Hammurabi?

Hammurabi was an ancient ruler of Mesopotamia and the first king of the Babylonian civilization. From 1792 to 1750 BC, he conquered many city-states and brought the Assyrians under his rule, uniting Mesopotamia into one kingdom.

The Code Of Hammurabi 

As mentioned, Hammurabi's Code contained 282 laws that Hammurabi stated he "received" from the Babylonian god of justice, Shamash. The Code of Hammurabi covered almost all aspects of Babylonian society, from criminal acts to property disputes, commerce, and familial disputes.

Key Points Of Hammurabi's Code

There were a few key points of Hammurabi's Code that you may recognize in today's legal system. While many countries worldwide have abolished such primitive practices, their principles remain.

An Eye For An Eye

It appears that Hammurabi hadn't heard "An eye for an eye makes the whole world blind" just yet, as several of the punishments within the Code dealt with "lex talionis," or the law that what was done to one party would be done to the other. This meant if one person cut off a hand, they would have their hand cut off. Or, an eye gouged out would be punished with the same.

Laborers Working For Pay

Rather than being kept as unpaid enslaved persons during Babylonian times (not to say that there were not slaves, there most definitely were), laborers in Mesopotamia were to receive shekels as payment for their work.

Building Codes

You may never have guessed that construction companies guaranteeing their work came from Hammurabi's Code. And while "building codes" were most certainly not a thing in Ancient Mesopotamia, the Code of Hammurabi did stipulate: "If a builder constructs a house for a man but does not make it conform to specifications so that a wall then buckles, that builder shall make that wall sound using his silver".

Persons Not Equal Before The Law

While certain writings in the Code of Hammurabi might make you think people were equal before the law, they were certainly not. Different degrees of punishment were handed out depending on the social status of the accused and victim. The three classes of people—gentleman, commoner, and slave—all had different punishments prescribed to them if they were victims of a crime.

One Crime? One Punishment

While "double jeopardy" was far from common in ancient Mesopotamia, the Code specified that one punishment would be given for one crime. The punishments for crimes were often severe, involving the loss of limbs or life.

The Presumption Of Innocence

Another standout legal principle from Hammurabi's Code was the presumption of innocence. The Code states: "If any one brings an accusation of any crime before the elders, and does not prove what he has charged, he shall, if it be a capital offense charged, be put to death". In other words, you'd better ensure you had a good case.

Providing Evidence To Prove Guilt Or Innocence

Another of the earliest incarnations of "innocent until proven guilty" was that evidence of a crime had to be brought before a judge, or "Galzu", as they were known, and one had to be convicted in court. You could no longer randomly accuse your neighbor of stealing your ox; you had to have evidence, like eyewitness testimony.

Established A Minimum Wage For Workers

Interestingly, the ancient Mesopotamian legal code was one of the first legal documents to establish a sort of minimum wage. For example, "Field laborers and herdsmen were guaranteed eight gur of corn per year". Meanwhile, a doctor who healed a "freeborn man" of broken bone was to receive five shekels.

The Archaeological Rediscovery Of The Code 

Despite being a mainstay in the legal world of the ancients, Hammurabi's Code was lost to the sands of time, only to be rediscovered in the 20th century by French archaeologist Jacques de Morgan. Working with a team of others, de Morgan unearthed the ancient stone slab in the Iranian city of Susa. Today, the Code of Hammurabi sits in the Louvre Museum in Paris, France.

Other Ancient Texts That Make Up Modern Law

While the Code of Hammurabi may have been the first ancient text to codify modern legal principles in a singular format, it wasn't the first legal text of Ancient Mesopotamia. That would be the Code of Ur-Nammu, the oldest legal code in the world.

The Code Of Ur-Nammu

The Code of Ur-Nammu, written between 2100 and 2050 BC in the Sumerian language, is accredited to Ur-Nammu of Ur, who ruled Sumer between 2112 and 2095 BC. It was the very first code to issue "IF" (Crime) and "THEN" (Punishment), a form of moral reasoning known as casuistry, or cause and effect.

How Did Ur-Nammu's Code Differ From Hammurabi's Code?

While only a few passages remain of Ur-Nammu's code, compared to the vast Hammurabi Code, there were a few major differences between the two of the earliest legal codes known to us. For instance, in the Code of Ur-Nammu, bodily damage done to one person was to be punished with remuneration rather than the Hammurabian "eye for an eye" method of punishment.

Surviving Laws From The Code Of Ur-Nammu

Despite being nearly three centuries older than Hammurabi's Code, some laws from Ur-Nammu's Code remain. Chiefly, the concept that murder is to be met with capital punishment remains—a practice that many American states still employ. 31 other laws from the Code of Ur-Nammu are currently on display in the Istanbul Archaeology Museum.

Roman Civil Law

Roman Civil Law laid the groundwork for much of the law that European and North American law is based upon. Known as ius civile, or "Civil Law," the Romans would begin to write down their laws in meetings around 451 BCE.

The Twelve Tables

A committee of 10 men, known as the decemvirs, was established in 451 BCE, and their job was to write down Roman law for the first time. Taking two years to write down the laws of the Roman Empire, the work they produced in 449 BCE was known as the Twelve Tables.

Laws Of Nations, People, And Nature 

While other civilizations may have previously understood the laws of nations, people, and nature, the Romans codified this understanding into three areas: Jus civile (Civil Law), laws that applied to everyone in all parts of the Roman Empire; Jus Gentium (Laws of Nations), laws that applied to all non-Roman citizens; and finally, jus naturale (Natural law), a law category applicable to all living creatures, both animal and human.

The Jurists Of Roman Law 

Similar to the Supreme Court of the United States, Roman law elevated jurists to positions of supreme authority. Although no jurists in Rome could implement the law, their job was to interpret it. Under the Emperor Justinian, they compiled all of Roman law into one great body of work.

Corpus Juris Civilis

This body of work became known as the Corpus Juris Civilis and was broken down into three parts: the Digest, the Code, and the Institutes. The Digest outlined the judiciary's legal opinions since the Twelve Tables was convened. The Code included the actual laws of the empire, including justifications. Finally, the Institutes were a summarized version of The Digest, intended to be a guidebook for law students.

Justinian's Greatest Contribution To European Law

This compilation of Roman law is said to be one of the greatest contributions to history that Emperor Justinian ever made. Roman law proved to be the foundation of Western civil law. It also formed the basis for English common law, which was established (ironically) by a Frenchman in 1066, when William the Conqueror became King of England.

English Common Law

The establishment of "common law," more specifically English common law, has its roots with William the Conqueror, who became King of England in 1066 after defeating Harold Godwinson at the Battle of Hastings. Several common law principles brought over from France were derived from Roman law. They include...

Stare Decisis

Stare decisis, which means "to stand by things decided" in Latin, establishes the principle of legal precedents. It provides the basis for English common law, where judges decide based on precedent rather than legal constitutions. While legal constitutions may provide an informative basis for an opinion, judges tend to use overarching legal precedents rather than the prescribed punishment for a crime.

The Magna Carta

While not as ancient as the Code of Ur-Nammu or Hammurabi's Code, the Magna Carta, or "Great Charter," was one of world history's most significant legal documents. Established by King John in July 1215, it was the first legal document to establish both individual rights and the rule of law in England.

What The King Could & Could Not Do 

Before the Magna Carta's creation, the King had extraordinary power. He could do as he liked, establish ownership over lands not originally belonging to the Crown, and order imprisonments, arrests, and much harsher punishments for those who defied him. Essentially, the King was the law.

The Clauses Of The Magna Carta 

While only four of the original 63 clauses in the Magna Carta are relevant today, many of the laws enshrined in it have been overwritten by British law since then.

No Free Man...

Among the four clauses that remain in effect, chief among them reads: "No free man shall be seized, imprisoned, dispossessed, outlawed, exiled or ruined in any way, nor in any way proceeded against, except by the lawful judgment of his peers and the law of the land".

No Denial Of Justice

Another foundational principle of the Magna Carta that remains written into British law today is: "To no one will we sell, to no one will we deny or delay right or justice". This principle is the precursor to the right to a fair and speedy trial under the Sixth Amendment to the Constitution of the United States.

The Universality Of The Magna Carta

It's suspected that the language of the Magna Carta, particularly "to no one" and "no free man," gave rise to an understanding that these laws would apply to everyone, not just the pauper or the lower classes of British strata but up to (and including) the monarch. This universality allowed for the improvement of British law throughout the centuries and the exportation of such principles to the United States and many other countries.

The US Constitution: From All That Came Before It

Adopting all of these principles throughout the centuries, the US Constitution is said to be one of the greatest living documents. Along with the Bill of Rights, it enshrined certain legal principles that had been carried over from centuries before into the foundation of the United States.

Constitutional Principles Adopted By Other Countries

The American Constitution contains many constitutional principles, such as the Separation of Powers, the Rule of Law, and a series of checks and balances on the powers of the government and head of state. Throughout the 19th century, many countries, such as Mexico, Denmark, Norway, the Philippines, and China, began to use the US Constitution to influence their establishment of democratic governance.
