The Letter of Peace is promoted by two cultural institutions, Ámbito de Investigación y Difusión María Corral and the Interdisciplinary Universitas Albertiana. These with a long working record in cultural and human coexistence contexts. The generous voluntary cooperation of many people from Barcelona and from many countries has been essential for the fast spreading that the Letter of Peace has had. In this regard, the social communication media reception –newspapers of several countries have published the complete document in more than a million copies- and the support from public and private institutions, have helped significantly the spreading and financing aspects.
It is important to emphasize the support granted by UNESCO and the sponsorship from Principality of Andorra. We want to thank all persons and institutions that throughout this time have helped us and support this arduous endeavor in favor of peace.
