Historically, the caste system is believed to have begun with the arrival of the Aryans in India around 1500 BC. The Aryans contained the first mention and a background of the elements that make up the caste system. The Aryans came from southern Europe and northern Asia with fair skin that distinguished them from the native Indians. The Aryans completely ignored the cultures of the Indian people and conquered regions in the north. The Indians were forced to move down south where the mountains were (Deshpande).
The Vaishyas are third in the Caste System, otherwise known as the common people. According to Yanjur Veda “Vaisya among men…brutes from the belly. As they have been created from the storehouse of food (belly) so they are the food (or inteneded to be enjoyed by others). Therefore, they (Vaisyas) are more numerous than others (among men) because many gods were created” (Rao 54). Some also say that the Vaishyas are from the thighs of the Purush. The Bhagavad-Gita further supports the claim that “Agriculture, breeding cattle, trade, (this) is the natural duty of the Vaisyas” (59).
