Here the kingdom started and along with that discrimination also started . The king have to form a strong government in form of a kingdom He started to form his ministry he appointed his friends and well wishers from all side of people. From here favouritism started it sows the seed for castism or sectarianism
In later period it creates a big trouble for Downcast people. I have a thought where the word downcast was derived from???.
According to me The King who divided the people in terms of his leadership qualities and popularity among the people and his wealth in the society for him king gave bigger posts like minister and other bigger administrative posts.
the people who have less in population and financially down are used as slavery workers . Upto here it gone smoothly that for the development of financial crises for downcast people the upper caste people provide some wages until their mentality of upper caste people gets change .
Generally human have the thought like if a man of downcast who works for upper caste people , once the life of the downcast man lifestyle changes " why should I have to work for you I'll can earn myself and for my family "
These words from the downcast people it created the EGO for upper caste people that " my slave have questioned me , then I have to show how great I'm" . From that moment their mentality of being humble orders are changed into forceful order "Do the work because you are my slave","your generations are slave for my generations too"
character of man changes between request into forceful order created sectarianism and castism
