Babar is crowned King of the Elephants, marries his cousin Celeste, and founds the city of Celesteville. Babar, who likes to wear a bright green suit, introduces a very French form of Western civilization to the elephants, and they soon dress in Western attire.
Among Babar's other associates are the monkey Zephir, the old elephant counsellors Cornelius and Pompadour (Pompadour was created for the Babar TV series), his cousin Arthur, and his children, Pom, Flora and Alexander. Later, a second daughter, Isabelle, was introduced. The Old Lady comes to live in the Kingdom as an honoured guest.
