The stamp commemorates the 80th anniversary of the Ventotene Manifesto (issued 31-08-2021). The Ventotene Manifesto is a political statement written by Altiero Spinelli while he was imprisoned on the Italian island of Ventotene during World War II. In it he proposes the idea of a European federation to prevent future wars. Therefore it is considered to be an inspiration for postwar unification of Europa and is currently pre-selected for the European Heritage Label.
