"From world-renowned historian and philosopher Yuval Noah Harari, the author of Sapiens, comes the second volume in the bestselling Unstoppable Us middle-grade series that traces human development from hunter-gatherer societies to cities and empires. Humans may have taken over the world, but what happened next? How did our hunter-gatherer ancestors become village farmers? Why were kingdoms and laws established? How did we go from being the rulers of Earth to the rulers of each other? And why isn't the world fair? The answer to all of that is one of the strangest tales you'll ever hear. And it's a true story. From cultivating land and sharing resources to building pyramids and paying taxes, prepare to discover how humans created civilization -- and suffered the consequences for it.
