odern Antisemitism appears in different forms and it is not always easy to unmask. The number of anti-Semiticincidents in EU Member States has risen significantly, also in the countries involved in the project where there is evidenceof high level of prejudice and misinformation about Jews, forms of Antisemitism and intolerance, increasingly exploitedby hate speeches online, particularly exacerbated since the 1st COVID lockdown (see “The rise of Anti-Semitism onlineduring the pandemic”, 2021, published by the European Commission. Starting from these premises, RELATION aims atdefining an innovative strategy that starts from a better knowledge of the Jewish history/traditions as part of the commonhistory/traditions, and puts in place a set of educational activities in IT, ES, RO and Belgium as well as online actionsin order to tackle this phenomenon. The method exploits the full potential of experiential learning for children (at least250), adolescents (at least 250) and young adults (about 2000) directly targeted by the actions. The learning experienceis devoted to promote a better knowledge of the Jewish culture and history starting from the traces, tradition and culturalexpressions. Moving from a solid research based activity (for mapping the state of the art, in each participating country,of anti-Semitic feelings and anti- Jewish prejudices/bias), the educational activities for pupils, the training activitiesfor teachers (about 100), as well as the delivering of an awareness online campaign tailored for young people (about2.000 directly involved with the aim to reach other 20.000) will be realized. Simultaneously, a semantic and target groupanalysis of Antisemitic contents on line will be realized during the whole project lifetime. The coverage of the activitiesis assured by a solid dissemination strategy. A final book will be published (paper and e-book) and a handbook will beprovided as guidance for transfer the methodology in other EU countries
