Since 1900, the world has undergone many changes and seen some huge technological leaps. War became far more deadly during the modern era and tens of millions died in two world wars. Mass media, telecommunications, the Internet and social media all helped spread knowledge and create a more globalised culture. Packed with beautiful illustrations, this book, in the Parallel History series for readers upwards of age nine, will help you to explore the major events and developments of the modern era, with timelines to show you when they took place around the world.
