A long, long time ago, people in Cambridge started schools to help children learn. These schools were different from others because they wanted children to learn all about the world around them. They called this "intellectual history".
Think of it like this: Imagine you want to learn about your family's history. You would ask your parents and grandparents questions about how they lived, what they ate, and what they believed in. This way, you can understand more about where you come from and how your family has grown over time.
In Cambridge schools, teachers wanted children to think the same way about history, but on a bigger scale. They wanted students to think about how people all around the world have lived and believed over the centuries. They wanted children to ask questions about why things were done a certain way in the past and how those actions have influenced the present.
So, in Cambridge schools, kids would learn about things that happened a long time ago, like wars, inventions and changes in societies. They would also talk about great thinkers and writers who had ideas that changed the world. But the most important thing they learned was how to ask questions and think deeply about what they were learning. This way, they could understand the world better and maybe even change it for the better in the future.
