You got the Warring States period of China and the feudal Kingdoms of Europe from 476 AD until centralisation of power and the growth of nationalism in the 16th century

It was after 1500 that armies in Europe got to 100,00 strong due to the centralisation of the kingdoms and the ending of internal petty Wars

Know it over 500 years since then and people don't know history so if you talke about what we are taking about

You will come across as mad because most people won't know what we are talking about

It's seems to me that the public historical knowledge goes back only to 1945
