Plan International was born in Spain in 1937, promoted by the British journalist John Langdon-Davies and by the English volunteer Eric Muggeridge. In its beginnings it was called "Foster Parents Plan for Children in Spain" (Plan of Host Families for Children of Spain) and its objective was to help children who were orphaned during the Spanish Civil War.

Plan International carries out relief activities in war zones, organizes emergency assistance plans and carries out long-term projects to help children, their families and their communities in developing countries.

For 80 years, Plan International has worked with children, their families and their communities. His tireless work based on social responsibility and transparency has cemented his reputation as a humanitarian aid agency highlighted by ethics, efficiency and commitment in each of his projects.
