R. C. Majumdar (not Mazumder) was my chachi's chacha, and related to us in various other ways. He was a nice man, and liked my father because of his own thorough knowledge of history, as well as the academic connections. Having said that, he was too right-wing for my personal taste, which is closer to my academic guru's guru, Sushobhan Sarkar, father of Sumit Sarkar. But even Sumit is not my personal choice of 'nationalist' historians (he was emphatically not a 'nationalist'); it is Jadunath Sarkar (no relation to the other two), who, with his thorough knowledge of Urdu and Persian, brought a great deal of original research to his studies of the Mughals, the Marathas, the Rajputs and of Indian history in general. It is surprising that more emphasis is not given to a study of these, as well as to Sanskrit for the study of ancient and early mediaeval India.
Among non-aligned, that is, non-'nationalist' historians, it is Kosambi head and shoulders over anybody else, with only Irfan Habib, and, to a lesser extent, Romila Thapar to challenge him.
Please.
You are a nice person, I'm sure. Worthy and all that. Please stay out of subjects that you don't understand and never will. And don't be abusive; this is a bad habit that has been noticed and commented upon before, and you really need to do something about it. Bad temper and bad language is unfortunately not a substitute for genuine learning.
