Caste System;
Brahmin: The Brahmins were the Priest/Priestesses of the society. They reached one of the highest caste. To reach this caste could take a lifetime. It is said they have lived through the cycle of Samsara many times and fully understand that they are Brahman. The Brahmins were one of the most honorable groups to lead the society in the early days of the Indus Valley.
Kshatriyas: Kshatriyas were warriors and aristocrats. This was also an upper status caste. Like the Brahmins they were considered to be one of the most honorable groups to lead the society in the early days of the Indus River-Valley.
Vaishyas: The Vaishyas were cultivators, artisans, and merchants.
Shudras: The Sudras were considered one of the lowest caste a person could be. They were landless peasants and serfs.

However, a person could lose their position and honor in the social hierarchy.

This painting is of the "whitest of the conch", or the highest level in the Brahmin caste system; the High Priest, getting fanned by people of a lower class.. This conception of such a time when daily life revolved around caste system blaintintly expresses the worship given to the priest. Not too conveniently, the priest represents the highest level in the caste system. This can be interpreted as evidence that class systems in the Indus River Valley civilization were highly, if not completely affected by caste systems. Caste systems are similar to class systems in that those in a higher caste are regarded to as superior, and are closer to "leaving" the cycle of being reborn over and over again as mortal. Once leaving the cycle (Samsara), they are closer to paradise, thus superior. So, when deciding who gets fanned by "luxurious fans" and who does the actual fanning, those in a higher cast will get fanned and those in a lower caste will do the fanning. This eventually marks the higher-class and more respected members of society, and the lower-class and less respected members of society.

This artifact helps historians understand how higher caste members were treated in comparison to lower caste members. Eventually one can interpret that if this treatment continues, it will eventually mold class systems in all of the Indus River Valley. Historians can extract that probably the rulers and high nobles of the land were most likely those acclaimed of being a part of a higher cast. I chose this artifact for that reason, with hope that this can serve as an appropriate example for class systems in the Indus River Valley.
