Boxen was the name C.S. Lewis and his brother gave to their childhood imaginary world.
As children, Clive Staples Lewis and Warren Lewis created stories about talking animals, invented countries, and political events. Their shared imaginative project was first associated with the name Animal-Land and later developed into Boxen, a blended name formed from the imaginary lands Boxonia and India.
The Boxen stories were written and illustrated in handmade books. They show how early Lewis practiced constructing fictional societies, histories, and competing viewpoints. The project was not the same world as Narnia, which Lewis invented and wrote about much later.
Because both settings include talking animals and invented kingdoms, readers sometimes treat Boxen as an early version of Narnia. The connection is developmental rather than canonical: Boxen belongs to the Lewis brothers’ childhood writings, while Narnia is the seven-book series published from 1950 to 1956.
