I'm not a history major, nor am i someone who wants to dive deep in history of a particular period. But i've had so many questions, and lots of dots that I didn't know how to connects. This book was the answer. Concise and on point, this book helped me pretty much connect all the dots. Absolutely the best history books for those who are mostly interested in the big picture. I've purchased 4 more books in the series (Sociology, Psychology, Philosophy, and religions book). They're all awesome books and are helping me fill all my knowledge gaps.
