The charity founded by J.K. Rowling in 2005 is Lumos.
Rowling established the organization as the Children’s High Level Group after becoming concerned about children living in institutions. The organization later became known as Lumos, taking its name from the light-producing charm in the Harry Potter books.
Lumos campaigns for children to grow up in families or family-based care rather than in large residential institutions. Its work has included advocacy, research, and support for changes to child-care systems in countries around the world.
The charity’s name can cause confusion because “Lumos” is also a fictional wand-lighting spell in the Harry Potter universe. The organization and the spell share a name, but the charity’s real-world mission concerns children’s rights and family care.
