RIEN CULP

Rien culp (pronounced as ryan kuhlp) is a Law French term that means "not guilty." It was used as a plea of not guilty in the past.

During the medieval times, when the legal system was still in its early stages, the accused would plead "rien culp" to deny the charges against them. For instance, if someone was accused of stealing, they would say "rien culp" to declare their innocence.

Another example of the use of "rien culp" is in the trial of Joan of Arc. When she was accused of heresy and witchcraft, she pleaded "rien culp" to deny the charges against her.

The term "rien culp" was used in the past as a plea of not guilty. It was a way for the accused to deny the charges against them and declare their innocence. The examples illustrate how the term was used in medieval times and in the trial of Joan of Arc.
