The history of the commercial law is connected with the middle ages (IX-XII centuries), but to explore it thoroughly, we have to make distinctions between history in the broad sense and history in the narrow sense of the word, depending on whether it concerns the development of the trade and legal institutions, together with the civil law or whether it concerns that evolution of commercial law when it is particularized and separated in a definite legal industry.
When we talk about the history of the commercial law in the broad sense of the word, the beginning of commercial and legal institutes may be found even in the most ancient times. The commercial law in the ancient times was not distinct. Its standards were regulated interfaces from the general civil law. The civil law in that era was developed satisfactorily for the requirements of rudimentary trade.
When we talk about the history of the commercial law in the narrow sense of the word, we talk about the development and evolution of the commercial law as a separate legal industry.
