Why did caste rankings vary from one region of India to another?

Caste rankings in India vary by region because the caste system is fundamentally organized around local jati groups rather than a uniform national hierarchy. While the fourfold varna model provides a theoretical, all-Indian framework, the actual social reality consists of thousands of distinct, endogamous communities with their own unique histories and local standing.1234

Regional variations in ranking occur for several reasons:

• Local Status Dynamics: The hierarchy is determined locally based on criteria such as ritual purity, occupation, and social customs. Because these factors are interpreted differently across regions, a group’s status can shift depending on the local social environment.14
• Dominant Castes: In many areas, a dominant caste emerges based on secular power—such as land ownership, numerical strength, and political influence—which can shape the local cultural tone and influence how other groups are ranked.13
• Historical Integration: Many castes originated from tribal groups or guilds that were incorporated into the Hindu social order at different times and places, leading to diverse local hierarchies.54
• Social Mobility: Castes frequently engage in efforts to improve their status through the adoption of upper-caste rituals or by leveraging economic and political power, a process that unfolds differently across various regions.162
