The article is about a project that was carried out between 2014 and 2017 by two countries: Nicaragua and Spain, on behalf of the organizations "Fe y alegría Nicaragua" and "Entreculturas (Fe y Alegría España)". It was an educative project among both nations that had two main objectives: promoting both local and global citizenship, and to give answer to violent situations that adolescent students hae to face in secondary education contexts, with special attention to the violence among equals or bullying.
