Arya Samaj (Sanskrit ārya samāja आर्य समाज "Noble Society") is a Hindu reform movement founded by Swami Dayananda on 10 April 1875.[1] He was a sannyasi who believed in the infallible authority of the Vedas. Dayananda emphasized the ideals of brahmacharya (chastity). There are 3–4 million followers of Arya Samaj worldwide.

Drawing what are seen to be the logical conclusions from these principles, the Arya Samaj also unequivocally condemns practices such as polytheism, iconolatry, animal sacrifice, ancestor worship, pilgrimage, priestcraft, the belief in avatars or incarnations of God, the hereditary caste system, untouchability and child marriage on the grounds that all these lack Vedic sanction.
