What are the major Indian castes how does their make-up resemble and differ from social structures of the egyptian and mesopotamian civilization?

The major Indian castes include the Brahmins (priests and scholars), Kshatriyas (warriors and rulers), Vaishyas (merchants and landowners), and Shudras (laborers and service providers). This Caste System is rigid and hereditary, emphasizing social hierarchy within a religious context. In contrast, Egyptian and Mesopotamian civilizations had more fluid social structures, with classes such as nobles, priests, commoners, and slaves, often allowing for social mobility. While all three systems exhibit hierarchical organization, the Indian caste system is unique in its strictness and spiritual significance compared to the more pragmatic social stratifications of Egypt and Mesopotamia.
