>Civil law actually goes back to the Romans
While what the Romans had is what eventually evolved into the modern civil law system, they lacked the primary feature of modern civil law: A single book (or otherwise well-defined collection of documents that can be re-published as a single book) that is "the law".

To my knowledge the first one of those was the Code Civil by Napoleon, marking it the first civil law system, as the term is understood today.
