Polish commercial law dating from 1934, i.e. the entry into force of the Commercial Code, is already eighty. This is a good opportunity to consider what its development over the centuries and millennia looked like. In this paper the author proposes to divide all this time into three periods. The development of commercial law, in relation to serious territorial and political system changes taking place in Poland at that time, was very stormy. After a great but short period before 1939, commercial law was in practice irrelevant. After 1989, it has been slowly formed as part of civil law. Unfortunately, the Civil Code still does not fully perform part of its functions and is not a primary source of commercial law.
