The charity founded by J. K. Rowling that supports disadvantaged children is Lumos.
Rowling founded the organization in 2005 as the Children’s High Level Group with politician and author Emma Nicholson. The charity focused on children separated from their families and living in institutions. In 2010, it adopted the name Lumos, taken from the light-producing spell in the Harry Potter books.
Lumos works to replace institutional care with family-based or community-based support. Its campaigns address children’s rights, family separation, and systems that place children in residential institutions when safer family care may be possible. The organization operates internationally and has worked with governments and local partners.
Lumos is a charitable organization, not a fictional group from the wizarding world. The name does come from Harry Potter, but the charity’s work is focused on real children and social-care systems. Rowling has also supported other causes, including multiple sclerosis research and literacy initiatives.
