Why is India organized into castes?

India is organized into castes primarily due to historical, social, and economic factors that date back thousands of years. The Caste System originally emerged from the division of labor in society, categorizing individuals into different groups based on their occupations and roles. Over time, these classifications became rigid, leading to social stratification and hierarchy, which have been reinforced by cultural and religious beliefs. Despite efforts to promote social equality, the caste system continues to influence various aspects of life in contemporary India.
