Unstoppable Us Volume 3

How Enemies Become Friends




From the author of the multi-million bestselling Sapiens comes the next volume in the incredible story of the human race, for younger readers.

Why is the world not always a peaceful place?
Why do we have wars?
And why do we sometimes . . . not?

The answer to these questions can be found in one of the strangest tales you'll ever hear. And it's a true story.

Find out about what exactly happened, thousands of years ago, when people from different tribes met. How they sometimes fought. But were sometimes able to live happily together.

You’ll discover how we were able to agree on rules and ideas for how life should go. Why wars were (and still are) often fought, and what we can learn from the past to make a more peaceful future.

From Ancient Rome to the Mongol Khans, from Carthage to Mongolia, travel deep into the past, and around the world, to discover how people became friends and enemies, and built the world as we know it today.
