Nationalism and Protectionism is a political ideology that prioritises national interests and economic self-sufficiency over global cooperation. It advocates for policies that protect domestic industries from foreign competition and emphasises the importance of national sovereignty. This approach often results in trade barriers, tariffs, and restrictive immigration policies, aiming to bolster domestic economies and preserve cultural identity. In an increasingly interconnected world, these ideologies challenge the principles of globalisation and international collaboration.

Nationalism and Protectionism matter because they significantly influence global trade dynamics and international relations. By prioritising national interests, these ideologies can lead to trade wars, economic isolation, and shifts in geopolitical alliances. Understanding their impact is crucial for policymakers to navigate the complexities of global economics and maintain international stability.

Scholars of international relations argue that Nationalism and Protectionism can reshape global power structures by challenging the liberal international order. Academic consensus suggests that these ideologies often emerge in response to perceived threats to national identity and economic security, particularly during periods of economic uncertainty. By analysing these trends, researchers can better predict shifts in international policy and economic strategies.
