With the Aryans' settlement in the Indus Valley and their subsequent expansion to the Ganges Valley, their oppression and exploitation of the local people became more and more intense, and the caste system became more and more strict. First, the Vedic literature appeared, and then the caste system gradually took shape, which laid the foundation for the dominance of Brahmins, which is also the foundation of Brahmins. Brahmins not only put the gods in primitive religion into the Vedas, but also added secular inequality to the scriptures, thus putting on a reasonable coat to eliminate the injustice of the lower class and consolidate the unshakable position of Brahmins. Brahmins use the power of God to consolidate their rule and gradually form Brahmanism.
The evolution and development of Brahmanism has always been accompanied by the evolution and development of caste system, and Brahmanism mainly embodies the interests and ideology of Brahmanism.
At the end of Vedas, Indian Brahmanism took shape. At that time, Brahmanism had systematized sacrifice, worship and doctrine, which constituted the focus of Indian traditional culture and had a great influence on later religions such as Jainism, Hinduism and Buddhism.
