In this handbook the authors focus on competences for democracy and thus on how to prevent and avoid anti-democratic phenomena like authoritarianism, violent radicalisation, extremism, hate speech or conspiracy theories. This material contains a set of new or refreshed educational methods, tailored to work specifically with social workers and youth workers. All of them should help them prepare to counter these tendencies. Handbook was developed in the project “Resilience through Education for Democratic Citizenship” (REDE), implemented in the programme “Democratic and Inclusive School Culture in Operation” (DISCO) of the European Commission and the Council of Europe.
