Book excerpt: Most people's knowledge of world history is hazy and incomplete at best. This updated No-Nonsense Guide gives a full picture, revealing the hidden histories and communities left out of conventional history books—from the civilizations of Africa, Asia, and Latin America to the history of women. The new final chapter includes material on the financial crisis and the world response to climate change. Chris Brazier is co-editor at New Internationalist. His previous books include Vietnam: The Price of Peace. He is principal writer for UNICEF's The State of the World's Children report.
