Under roman law, someone accusing another person of a crime needed belief that the accused was guilty. proof that a crime had been committed. a lawyer willing to take the case to trial. a witness to vouch for the accuser’s character.

The correct answer is: "proof that a crime had been committed"

The Roman law was the legal system that governed the citizens of Ancient Rome, in a historical spectrum whose starting point is placed on par with the founding of Rome (according to tradition, on April 21, 753 BC). ) and that extends until the middle of the 6th century AD, time in which the compiler work of Emperor Justinian I took place, which since the Renaissance was known as the Corpus Iuris Civilis. The Corpus is without doubt the most influential legal text in the history of mankind, because it is the basis of the law of many countries around the world.

During the apogee of Rome, the evidentiary right reached an important scientific development that can be seen represented in the studies of Aristotle, as Rhetoric in which there was a logical conception, alien to all prejudices of a religious order to evaluate the proof.
