GURUSHABAD RATANAKAR MAHAN KOSH, more popularly known by its shorter title Mahan Kosh, the great dictionary, by the celebrated man of letters and lexicographer, Bhai Kahn Singh, of Nabha, is a work unexcelled for its neatness and refinement of expression and monumental in its scope and size. It would indeed do justice to the title "Encyclopaedia." It is amazing how an individual conceived and planned a work of such a vast dimension and how he accomplished it single handed in a single lifetime.
Ham Hindu Nahin, by Bhai Kahn Singh, lit. "We, i.e. Sikhs, are not Hindus," is a clear-cut declaration of Sikh identity registered by a Sikh scholar and intellectual towards the close of the nineteenth century. The statement constitutes the basic dictum of the book which appeared under this challenging title in 1898. In the signed introduction to the work, the author puts down HB as his initials. Decoded, the initials stand for Kahn Singh. The book was registered under this title in the Punjab Gazette on 30 June 1899 at number 447. The author\'s name, Kahn Singh, started appearing in the book from 1907. The book recalled the days of long-drawn polemic between Hindus and Sikhs.
KHALSA DEFENCE OF INDIA LEAGUE was formed on 19 January 1941 at Lahore with the object of launching a movement among the Sikh masses for increased military enlistment for the defence of the country during the critical years of World War II and for maintaining and strengthening the special position of the Sikhs in the Indian army. A report prepared by a committee headed by an English General appointed by the British to look into the causes of the slow rate of Sikh recruitment sent to the Punjab Government was suppressed by the Premier, Sir Sikandar Hayat Khan.
