Abstract
India is one of the four ancient civilizations in the world. The Indus River civilization was created between 2500 and 1500 BC. Around 1500 BC, a branch of the Aryan people who originally lived in Central Asia entered the South Asian subcontinent, conquered the local indigenous people, established some small slave states, established the caste system, and the rise of Brahmanism.

India is the world's second most populous country, with rich cultural heritage and tourism resources. India is one of the BRICS countries today and also one of the fastest developing countries in the world. It has become an important exporter of global software, finance, and other service industries. But at the same time, it is also a developing country with extremely uneven distribution of social wealth, and the issue of caste system is more acute
