Lajpat Rai (1865-1928), a renowned leader simultaneously of Congress, Hindu Mahasabha and Arya Samaj, “long before Mohammad Ali Jinnah pronounced his poisonous Two-nation theory in 1939 and demanded a ruinous partition of India in 1940, the Mahasabha leaders like Lala Lajpat Rai and Savarkar had openly advocated this theory…”[x] In 1989, Lajpat Rai while writing on the theme of the Indian National Congress in the Hindustan Review declared that “Hindus are a nation in themselves because they represent all their own.”[xi] By 1924 he was more articulate in summarizing his Two-nation theory. He wrote: “Under my scheme the Muslims will have four Muslim States: (1) The Pathan Province of the North Western Frontier (2) Western Punjab (3) Sindh and (4) Eastern Bengal. If there are compact Muslim communities in any other part of India, sufficiently large to form a Province, they should be similarly constituted. But it should be distinctly understood that this is not a united India. It means a clear partition of India into a Muslim India and a non-Muslim India.”[xii] [Italics as in the original]
