The Varnas system began during the Aryan invasion of India. The Varna system, which is known as the caste system, divides society into 4 categories:
Brahmins are educators like scholars, teachers, gurus; and spiritual leaders such as priests.
Kshatriyas are the "warriors" whose roles are to protect society. The term can be translated as "authority," so these people are usually kings, rulers and the like.
Vaishyas are productive class, or simply the businessmen. They are in charge of agricultural businesses and trading. They ensure the wealth of the society.
Shudras are coined as the unskilled workers. They are in a sense, the "servers". They tend to the higher classes and work for them and are expected to remain loyal to them.
