It's said commonly that the numerous "Histories of the World or the Mankind" ever published are really only Histories of the White, Christian, Western men. This book it's not exactly as that, but approaches in some sense.
The book is reasonably good between his limits, but this series of "50 facts about... everything" from Ed. Quercus has the problem that too much information has to be compressed into very few pages. Each chapter occupies exactly 4 pages.
Well, another people from another countries should have his point of view. I, as Spanish can say this is a History almost only for English speaking people, with some concessions to cultures of antiquity, Rome, Egypt, China and others.
We see an example of omission: in 1571 there was a crucial confrontation, with little doubt as important as D Day in II WW, the battle of Lepanto, when Spanish Army and fleet with an aid from the Vatican and Venetian Republic defeated the big menace of the Turks in Europe. This is reduced to a one or two minute mentions. It's only one example, but for me, as important than USA Civil War. So, you must judge if you are interested in such biased history.
