This special issue invites scholars to explore the intersection of leadership and systems, specifically interrogating leadership's role in fundamental processes of change within structures, processes, and relationships. A focus on systems change connects the study of leadership to larger debates about how to grapple with grand challenges such as climate change and digitalization, as well as confronting pressing problems such as economic inequality and various forms of discrimination (Grint, 2023;Harrison, Kaesehage, & Leyshon, 2019).
