We have read books about the Liberation war of Bangladesh, we watched films that depicted the sacrifices of our freedom fighters, yet politicians have tried to use this glorious history for their own interest. Muhammad Zafar Iqbal, a renowned and popular author of modern Bangla literature has tried to give a short narrative of this history from a neutral point of view on his book "Muktijuddher Itihash ( History of Liberation War)" . The great thing is we can download this book for free and read the whole book in just one sitting. This book is available both in Bangla and English in pdf format.
