Which religion is known for its caste system?

Hinduism is known for its caste system, which is a complex social hierarchy that has historically divided society into distinct groups. These groups are generally referred to as varnas, and include categories such as Brahmins (priests and scholars), Kshatriyas (warriors and rulers), Vaishyas (traders and agriculturists), and Shudras (laborers and service providers). This system has deep cultural and scriptural roots within Hindu texts, such as the Manusmriti, and has influenced social structures in India for centuries.

The caste system traditionally dictated social interactions and occupational roles, often restricting mobility between the classes and resulting in long-lasting social stratifications. While the modern Indian constitution has sought to abolish caste discrimination and promote equality, the historical significance of Hinduism's association with the caste system remains a critical area of study in understanding social dynamics in South Asia.

In contrast, other religions mentioned in the question do not have a similar social stratification system rooted in their beliefs. For example, Buddhism emerged partly as a response to the rigid social hierarchies of Hinduism and promotes the idea of egalitarianism. Confucianism emphasizes social harmony and roles but does not establish a caste-like system as seen in Hindu
