    Nathaniel Bowditch grew up in a sailor’s world—Salem in the early days, when tall-masted ships from foreign ports crowded the wharves. But Nat didn’t promise to have the makings of a sailor; he was too physically small. Nat may have been slight of build, but no one guessed that he had the persistence and determination to master sea navigation in the days when men sailed only by “log, lead, and lookout.” Nat’s long hours of study and observation, collected in his famous work, The American Practical Navigator (also known as the “Sailors’ Bible”), stunned the sailing community and made him a New England hero.

    Sometimes it's murder, sometimes it's by accident, and sometimes it's because they were so ludicrous they didnt deserve to exist in the first place. Occasionally they explode violently. A few slip away almost unnoticed. Often the cause of death is either 'got too greedy' or 'Napoleon turned up'. Now and then they just hold a referendum and vote themselves out of existence.This is an atlas of 48 nations that fell off the map. The polite way of writing an obituary is: dwell on the good bits, gloss over the embarrassing stuff. This book refuses to do so, because these dead nations are so full of schemers, racists, and con men that it's impossible to skip the embarrassing stuff.Because of this - and because treating nation-states with too much reverence is the entire problem with pretty much everything - these accounts are not concerned with adding to the earnest flag saluting in the world, however nice some of the flags might be.

    At the center of this fascinating period is the document that has become the root of modern freedom: the Magna Carta. It was a time of political revolution and domestic change that saw the Crusades, Richard the Lionheart, King John, and—in legend—Robin Hood all make their marks on history.The events leading up to King John’s setting his seal to the famous document at Runnymede in June 1215 form this rich and riveting narrative that vividly describes everyday life from castle to countryside, from school to church, and from hunting in the forest to trial by ordeal. For instance, women wore no underwear (though men did), the average temperatures were actually higher than they are now, and the austere kitchen at Westminster Abbey allowed each monk two pounds of meat and a gallon of ale per day. Broad in scope and rich in detail, 1215 ingeniously illuminates what may have been the most important year of our history.

    It can offer examples to inform our decisions and guesses about the consequences of our actions. But we should be wary of looking to history for dogmatic lessons.We should distrust those who abuse history when they call on it to justify unreasonable claims to land, for example, or restitution. MacMillan illustrates how dangerous history can be in the hands of nationalistic or religious or ethnic leaders who use it to foster a sense of grievance and a desire for revenge.
