সমাজ ও সভ্যতার ক্রমবিকাশ(হার্ডকভার)

This book would have been great, only if it was not written with bias, rather it was written with biases. Bias of communism. This is the reason why I really didn't like the book, but this book is not so bad, and it really shows us some or other degree of social order in particular times.
