What is the border in which the caste System that team in India plays the first development at the top and the most recent development at the bottom

The caste system in India follows a hierarchical structure, with the highest castes at the top and the lowest castes at the bottom. The exact border or boundary is not clearly defined, as the caste system is a complex and evolving social system. However, traditionally, the four major varnas (or main caste categories) are considered to be at the top, in the following order:

1. Brahmins (priests, scholars, and teachers)
2. Kshatriyas (warriors, rulers, and administrators)
3. Vaishyas (merchants, farmers, and businessmen)
4. Shudras (laborers and servants)

Below these four varnas, historically, are the Dalits, also known as Scheduled Castes or Untouchables. They have often been marginalized and faced discrimination due to their historically low social status.

It is important to note that these descriptions provide a simplified overview of the caste system, and there are numerous sub-castes and thousands of caste groups in India. Additionally, efforts have been made over the years to promote social equality and reduce discrimination based on caste, especially through affirmative action policies and legal reforms.
