How was historical migration of India?

Historical migration in India has been shaped by various factors, including trade, invasions, and colonialism. Ancient trade routes facilitated the movement of people, while invasions by groups such as the Aryans and Mughals led to significant demographic shifts. The British colonial era further intensified migration through the indentured labor system, which sent many Indians abroad, particularly to the Caribbean, Africa, and Southeast Asia. Post-independence, internal migration surged due to urbanization, economic opportunities, and regional conflicts.
