Lawyers originated in ancient Rome. * * * Proceedings against Rome (510 B.C. or 509 ~ 30 B.C.) must be based on notice and legal process from the consul or praetor. As the number and complexity of laws and notices increases, parties require the assistance of persons familiar with the law during litigation, especially during court arguments. Therefore, from the end of the ***** system to the beginning of the imperial system (the second half of the 1st century BC), the garrison appeared.
By the end of the 5th century, those who served as defenders had to study law and obtain qualifications in major cities. They gradually formed an industry, formed their own professional group, and became full-time lawyers.
During the feudal period, most countries abolished ancient debate proceedings and replaced them with religious inquisitions, which made lawyers useless. Some countries, such as France in the early Middle Ages, retained the system of lawyers, but mainly for religious courts, and the position of lawyer was held by monks. Lay courts sometimes allowed defense, but only monks could perform this function.
After the 12th century AD, French secular courts prohibited monks from serving as defenders, and instead used professional lawyers who had received feudal legal education and had taken the oath of attorney to serve. However, their authority was greatly restricted, and even existed in name only.
