Integration of global markets. As globalization develops, countries' economies become increasingly interdependent. As a result, nation-states' ability to act independently in the economic field has weakened. This has fueled a revival of economic nationalism in some countries. This can be observed in protectionism policies and trade barriers, as well as in "buy local" trends that are trying to secure local economies and exclude damage from global trade. In culture, it can manifest due to a loss of local character in favor of a homogenization effect. This may manifest as threats from strong and influential cultures to the well-being and identity of smaller or weaker ones. This can provoke new nationalistic and localism movements that pop up to support and prove local traditions, language, and way of life. Another factor that may inflame nationalism is the dissolving of the nation-state's absolute authority by the global governance structures and by its participation in multinational alliances. When that happens, nationalist causes may appear to Americans as a corrective to the undue influence of foreigners.

In the last few years, populist nationalism has become more prominent in many countries, including major Western democracies. Nationalist politicians and political parties have become more popular by promoting tougher immigration policies, national sovereignty, and opposition to elite globalization. Globalization has also enabled ethnic and secessionist' movements to organize and communicate rapidly. These movements employ global networks to garner international support and legitimize their causes, which may exacerbate nationalism among diverse minority populations. Nationalist organizations may now more successfully plan, mobilize, and transmit their messages because of the digital revolution, which has made nationalist emotions more broadly and swiftly disseminated. Nationalist groups have maintained and resurrected in large part because of social media platforms.

Nationalism seems to be growing in many ways, driven by the uncertainties and difficulties brought forth by globalization. Increased nationalist feelings are often a reaction to global influences seen as dangerous or unstable, brought on by economic inequality, cultural shifts, and political upheavals. Not Just Reversing The truth has been more about adaptation than outright collapse, even if it was previously believed that globalization would signal the end of the nation-state and nationalism. Using the instruments and processes of globalization to advance their own goals, nationalist groups have changed and adapted to the new global environment. Regional situations might cause the trend to differ significantly. For instance, in the European Union, there has been a strong drive for integration, and major nationalist groups are seeking more autonomy and even leaving the Union.
