The historical characteristics of ancient India (600 BC-800 AD) lie in the establishment of Varna system and its transformation to caste system, the assimilation of tribal society and its transformation to the state, the rise of land-grant system and its transformation to feudal system, the decline of Buddhism, the rise of neo-Brahmanism and its transformation to Hinduism.
Ancient Indian civilization was discovered in 1922. Because its site was first excavated in Halaba, India, it is usually called "Halaba culture"; Because these sites are mainly concentrated in the Indus Valley, they are also called "Indus Civilization". The age of Halaba culture is about 2300 BC to 1750 BC.
