Thumbelina was born as Princess Maya in a village filled with tiny people. When she was born, she was betrothed to marry Prince Horace. However, one night the village was attacked by circus owner Roman. He wanted to capture the tiny people to use in his circus. He failed to kidnap them, but managed to capture Princess Maya and Prince Horace as they were only children. However, Prince Horace managed to escape, but Princess Maya remained Roman's prisoner. He made her part of his circus and named her Thumbelina. Thumbelina lived an unhappy life as she was never shown any kind of love and was always taken advantage because of her size. This lead to Thumbelina feeling incredibly alone in the world and believed there was on one else like her. However, Thumbelina did have a heart necklace which was the only thing she has from her real home, but she was unable remember anything else from her past.
