The guide addresses the pressing issue of shrinking civic space, a phenomenon where authoritarian tendencies erode the independence of courts, media, and CSOs. It introduces the concept of narrative change as a critical tool to counteract defamation, vilification, and public mistrust targeted at civil society. The document highlights ten core lessons, such as engaging the ‘movable middle,’ anchoring narratives in unifying values, and using storytelling to humanise CSOs’ work. With practical examples, like the #Azamatbol campaign in Kazakhstan, and insights into countering attack narratives, the guide empowers CSOs to strategically communicate their role in upholding democracy and human rights. This resource is essential for organisations seeking to foster societal trust and ensure their sustainability in the face of increasing challenges.
