This chapter investigates the growing influence of small and emerging countries (S&E) on the United Nations Security Council (UNSC) over the last two decades, undermining large powers’ long-held supremacy in global decision-making. By focusing on Türkiye, India, the United Arab Emirates (UAE), and Singapore, the study investigates the reasons and election methods that allow S&E countries to gain UNSC membership. The chapter examines how these states use diplomatic savvy, issue-specific expertise, and strategic alliances to impact discourse and outcomes inside the UN Security Council. The study demonstrates that, despite their limited material resources compared to the P5, S&E powers serve as essential change agents, fostering more inclusive and representative governance. Case studies demonstrate the range of techniques used by growing middle powers like Türkiye and India, as opposed to smaller states like the UAE and Singapore. The chapter finishes by evaluating the tangible outcomes of S&E membership, their impact on UNSC debates, and the broader implications for global governance.
