How the Caste System Evolve? is it democratic or not?

The caste system evolved from a social stratification and social restrictions to kept a sense of order, and peace among the people and for people to have their own place among each other and accept that the caste system is the way to keep society from disintegrating to chaos. I think it's not democratic because there form of government where not derived from the people, either by direct referendum or by means of elected representatives of the people. There form of government are based on hereditary or by genes and also the class of peoples are defined by thousands of endogamous hereditary groups, often termed jatis or castes. And the untouchables are being group to the lower peoples because they don't believe in castes system.
