Which code of honor was written first the code of chivalry or the code of bushido?

The code of chivalry was developed in medieval Europe, primarily during the 12th century, while the code of bushido, which governs the samurai class in Japan, began to take shape in the late 12th century but was more formally articulated in the 17th century. Thus, the code of chivalry predates the more defined version of bushido. However, some elements of bushido existed earlier in Japanese culture. Overall, the code of chivalry is generally considered to have been established first.
