Maharshi Dayanand Saraswati (pronunciation ) (12 February 1824 – 30 October 1883) was an Indian philosopher, social leader and founder of the Arya Samaj, a reform movement of the Vedic dharma. He was the first to give the call for Swaraj as “India for Indians” in 1876, a call later taken up by Lokmanya Tilak.

Denouncing the idolatry and ritualistic worship, he worked towards reviving Vedic ideologies. Subsequently, the philosopher and President of India, S. Radhakrishnan called him one of the “makers of Modern India”, as did Sri Aurobindo.Those who were influenced by and followed Dayananda included Rai Sahib Pooran Chand, Madam Cama, Pandit Lekh Ram, Swami Shraddhanand, Shyamji Krishna Varma, Kishan Singh, Bhagat Singh, Vinayak Damodar Savarkar, Bhai Parmanand, Lala Hardayal, Madan Lal Dhingra, Ram Prasad Bismil, Mahadev Govind Ranade, Ashfaq Ullah Khan, Mahatma Hansraj, Lala Lajpat Rai, and Yogmaya Neupane.He was a sanyasi (ascetic) from boyhood and a scholar.

He believed in the infallible authority of the Vedas. Dayananda advocated the doctrine of Karma and Reincarnation. He emphasized the Vedic ideals of brahmacharya, including celibacy and devotion to God.

Among Dayananda’s contributions were his promoting of the equal rights for women, such as the right to education and reading of Indian scriptures, and his commentary on the Vedas from Vedic Sanskrit in Sanskrit as well as in Hindi.
