Answer:
Similarities- Both systems stratify society based on ascribed status, although the estate system is a bit more flexible. Both systems use religious or spiritual ideology to justify stratification. Both dictate occupation, marriage, and relationship options.
Differences- In the estate system, the nobles are born into that class. They claim their authority through the divine right of kings. Members of the clergy are born into nobility and then become priests, while commoners rarely move out of their position. Unlike the caste system, the estate system no longer exists. The caste system, though no longer legal, still exists in places such as India. Hindus based the caste system on the religious ideology of reincarnation. Indians cannot change castes.
