A more thorough explanation:

LEX ROMANA

Lex Romana is a Latin term that refers to the legal system of ancient Rome.

The legal system of ancient Rome was one of the most influential in history. It was based on a set of laws and legal principles that were developed over centuries and applied throughout the Roman Empire. The lex Romana was the body of law that governed the lives of Roman citizens and non-citizens alike.

One example of the lex Romana is the Twelve Tables, a set of laws that were written down in the early Roman Republic. These laws covered a wide range of topics, from property rights to criminal offenses. Another example is the Justinian Code, a collection of laws and legal principles that was compiled in the 6th century AD and served as the basis for much of European law for centuries to come.

The examples of the Twelve Tables and the Justinian Code illustrate the definition of lex Romana by showing how the legal system of ancient Rome was based on a set of laws and legal principles that were developed over time and applied throughout the Roman Empire. These laws were designed to ensure fairness and justice for all, and they continue to influence legal systems around the world today.
