The Ambassadors of Non-Violence is the first Erasmus+ project implemented by the association SOS Rijeka - Center for Non-Violence and Human Rights as the lead organisation. The project, beyond its formalisation and application, has actually grown organically, evolving from the growth of a preventive-educational programme that constitutes one of the four strategic programmes of the association. Since 2014, the SOS Rijeka Association has been conducting preventive-educational workshops in high schools as part of the "Love Loves, It Does Not Hurt" project, aiming to reduce the incidence of violence in the romantic relationships of young people. Since 2020, in collaboration with the University of Rijeka and local human rights organisations, it has participated in the implementation of the “communis” course "Gender, Sexuality, Identities - from Oppression to Equality." Both initiatives have resulted in an increasing interest among young people to engage with the association as volunteers or programme participants, contributing to reducing the incidence of gender-based violence in the local community and becoming active and assertive citizens. From the beginning, the association has nurtured the idea of creating programs for young people 'from the bottom up,' involving young people who have chosen to participate. With the aim of addressing current issues and raising awareness and knowledge, the project and its activities have involved young individuals in advisory roles. Regarding the project's issues, violence occurs in all societal structures and is a major cause of death for individuals aged 15 to 44 worldwide (WHO, 2002). According to the Convention on the Rights of the Child, the educational system is obliged to educate children and young people about respecting the rights and freedoms of others and prepare them for a responsible life in a free society, promoting a culture of peace, tolerance, equality, and justice. A 2006 study conducted by the CESI association revealed that the majority of young people aged 16 to 19 already have experience in relationships, and many consider violence in relationships a serious problem among adolescents. In 2012, the same association conducted a study and analysis of strategies and programmes for preventing violence in the romantic relationships of young people, emphasising the role of civil society organisations as key stakeholders in prevention programmes. The importance of a gender perspective in addressing violence in the romantic relationships of young people was also highlighted, emphasising the significance of educating young people about gender stereotypes and prejudices. Unfortunately, the situation has not changed significantly over the years, and recent research by the CESI association (2018) shows that 58% of young people have experienced some form of violent behaviour in romantic relationships, with 70% stating that they have experienced such behaviour for an extended period. Considering that in Croatia civic education does not have its place as a separate subject in the formal education system, it is extremely important to address topics such as gender equality, human rights, and the promotion of non-violence through informal programs, such as those of the SOS Rijeka association. The goal of the Ambassadors of Non-Violence project was precisely to provide young people with a platform through which they can speak out about (non)violence, gender equality, and human rights in their unique way, sharing the knowledge and experience of SOS Rijeka, an important organisation addressing violence since 1999. As a medium for this, young people chose information and communication technologies (resulting in a social media campaign) and film (the project, in partnership with the Filmaktiv association, produced a documentary film titled "I Breathe," addressing emotional violence in romantic relationships). What was also crucial at the project application stage was conveying the voice of young people to decision-makers and other important stakeholders in youth work. For this reason, guidelines for decision-makers on working with young people on the topic of gender-based violence were developed as part of the project.
