The final idea that was modified in modern times was the concept of Bushido. Bushido was the warrior code and laws of feudal Japan, that while having cultural surface differences, was at its heart not that different from the code of chivalry or any other similar system in other cultures. In later years, the code of Bushido found a resurgence in belief following the Meiji Restoration. At first, this allowed Japan to field what was considered one of the most professional and humane militaries in the world, one respected by friend and foe alike. Eventually, however, this belief would become a combination of propaganda and fanaticism that would lead to the Second Sino-Japanese War of the 1930s and World War II.
