Before the early medieval period (from the Heian to Kamakura periods), the general public (peasants etc.) were regulated only by the laws established by rulers, such as the Ritsuryo codes, court noble law, honjo (proprietor or guarantor of manor) law, and samurai law.
中世前期（平安時代～鎌倉時代）までは、民衆（百姓など）を規制する法令は、律令・公家法・本所法・武家法など支配者により定められたものしか存在していなかった。
