What Happened When in the World is my new favourite kids book! This is a history book for kids filled with really interesting facts. It covers the ancient world to the 21st century with a double page spread for each featured time period. It’s very visual, with maps and drawings to illustrate the historical period in question and small chunks of written facts. What I really love is some of the more unusual eras mentioned such as the section on the Mongols or the Great African Kingdoms – not something you find in every history book! I challenge you not to find yourself reading this book with some “Oh, I didn’t know that” moments!
