Hinduism has been in England since the early 19th century.
Occasionally there were Hindu scholars, philosophers, reformers and also visitors from the princely states of India. Raja Ram Mohun Roy (born in India in 1772) was founder of a Hindu reform movement in India. He came to England in 1829 to visit his Christian friends. He also had audience with King William the IV. Roy died in Bristol four years later.
The great orientalist and reformer Sir R.G.Bhandarkar visited London in 1874.
Swami Vivekananda visited England in 1896, having addressed the World's Parliament of Religions in Chicago in 1893. Early Hindus in England were usually students, sometimes with exceptional ability. Rabindranath Tagore (later a Nobel Laureate) came to England in 1878, returning in 1880. Ramanujan, a mathematical genius and an orthodox Hindu, spent almost five years (1914-19) at Cambridge University. Professor Sir Sarvepalli Radhakrishnan was Spalding Professor of Eastern Religions and Ethics at the University of Oxford from 1939 until 1952. Hinduism had already received widespread attention in the Victorian era largely due to the work of the Theosophical Society and emergence of the new field, Indology.
Mahatama Gandhi studied law in England.
