Has South Africa Overtaken Nigeria as Africa’s Giant?

The research paper examines whether South Africa has eclipsed Nigeria as Africa's dominant power. While Nigeria maintains significant demographic and resource-based weight, the author argues that South Africa has leveraged multilateral institutions, a diverse economy, and a value-driven foreign policy to achieve greater global visibility and influence. The analysis highlights Nigeria's internal security challenges and strategic drift as factors that have diminished its international standing, while noting that South Africa faces its own domestic vulnerabilities, including energy crises and high unemployment.

• Nigeria's claim to continental leadership is supported by its massive population, projected to reach 400 million by 2050, and its status as Africa's top oil producer with the tenth largest proven oil reserves globally.
• Nigeria's ability to project hard power and provide regional security in West Africa has declined due to internal security crises, including the Boko Haram insurgency, the Islamic State West Africa Province, banditry in the North West, and secessionist threats in the Niger Delta and South East.
• South Africa has established itself as a global diplomatic player through its membership in the G20 since 1999 and BRICS since 2010, whereas Nigeria only joined BRICS as a 'partner country' in 2024.
• South Africa's foreign policy is characterized by a strategic narrative of human rights and international law, exemplified by its 2023 legal challenge against Israel at the International Court of Justice (ICJ) regarding genocide in Gaza.
• South Africa's institutional depth and global influence are bolstered by a more diverse industrial and services base and a vibrant civil society, contrasting with Nigeria's heavy economic reliance on crude oil, which accounts for almost 69% of its exports.
• Despite its diplomatic ascent, South Africa faces significant internal risks, including energy crises, high unemployment, and persistent inequality, as well as potential diplomatic pushback from Western nations over its alignments with Russia, China, and Iran.
