The fictional land in C.S. Lewis’s early childhood stories was called Boxen. Lewis and his brother Warren created the imaginary world during their youth, combining two earlier invented countries, Box and India.
Boxen featured histories, governments, animals, and political events that the brothers recorded in notebooks and stories. Lewis’s early fascination with constructing this detailed world is important because it shows that his interest in imaginary societies began long before he wrote Narnia. The material was not originally created as a professional publishing project; it was a private imaginative activity shared with his brother.
Boxen is often confused with Narnia because both are associated with Lewis’s invented worlds and talking animals. They are separate creations. Narnia emerged decades later as the setting of The Chronicles of Narnia, while Boxen belonged to Lewis’s childhood writing and was not the setting of his published fantasy series.
