In Japan a well-developed feudal regime flourished. It is really one of the glories of that nation to have intuited the principles of wisdom that presided over the foundations of medieval feudalism. To have intuited this in such a way that, comparing the Japanese medieval regime with the medieval regime in the West, there are similarities.
One of the characteristics inherent to the feudal regime is a certain patriarchal sense of the greatness of the feudal lord, as a father and as a protector of those who are his vassals. In the feudal conception - this must be horrifying to the ears of Catholic progressives - the terms father and sir are similar. The father is master of his children. You are the father of your vassals. You assume the full protection of your vassals and defend them against external enemies. Such defense of the vassals is up to the lord rather than the king.
It follows that some notes present in the feudal constructions of the Middle Ages are factors of security, solidity and stability. But, simultaneously, such notes reflect a certain height, a certain challenge, a certain boldness typical of a power that is continually at war. War often led to exaggeration, even against real power. This came to be greatly weakened in Japan, partly because of feudalism, just as it was, at some point in the Middle Ages, in France.
Mita system was one of the best inventions of the Incan government! Enormous construction of structures and highways was made possible because of the system. In the system all the people worked for the government for a certain period of time. This labor was free to government. During the Incan period, people were needed to work only 65 days to provide food for their family. So they had ample time afterwards. When it was someone elses turn,they had to join Mita. It was like the public service systems of modern times. Government took care of the family who was absent in the while working in MIta. In Mita people worked in building highways, construction of Emperor and nobles, monuments, bridges,houses, temple fields, Emporer fields and also mines.
