The 21st century has seen significant changes in the way nationalism is perceived and expressed throughout the world. Nationalism, defined as a political ideology that emphasises the interests and culture of a particular nation, has undergone a number of transformations in response to changing global political and economic conditions.

Some of the expected changes in the nationalist mindset throughout the world in the 21st century include:
- Rise of Populist Nationalism: Populist nationalism movements, characterised by anti-immigrant sentiment, xenophobia, and a rejection of globalism and international cooperation, have gained significant support in many countries in Europe and North America. These movements have led to the rise of leaders such as Donald Trump in the United States, Matteo Salvini in Italy, and Viktor Orban in Hungary.
- Intertwining with Identity Politics: Nationalism is expected to become more intertwined with identity politics in the 21st century. Nationalism will become more tied to issues of race, gender, sexuality, and religion, as different groups within a nation compete for power and resources. This is likely to lead to increased polarisation and division within societies, as well as the rise of new forms of identity-based nationalism.
- Transnational Nationalism: The 21st century is also likely to see the rise of transnational nationalism, which emphasises the importance of shared cultural and historical ties across borders, rather than the traditional focus on a single nationstate. This form of nationalism may be seen as a response to the increasing interconnectedness of the world and the growing sense of global citizenship.
- Rise of Digital Nationalism: The increasing use of social media and other digital platforms to spread nationalist ideologies and mobilise support has been a significant change in nationalism in the 21st century. These platforms have allowed nationalist movements to bypass traditional gatekeepers such as the mainstream media and reach large audiences directly.
- Eco-Nationalism and Feminist Nationalism: The 21st century has also seen the emergence of new forms of nationalism, such as eco-nationalism and feminist nationalism. Eco-nationalism emphasises the importance of protecting the environment and preserving the natural resources of a particular nation, while feminist nationalism focuses on the rights and interests of women within a particular nation.
- Resurgence of Nationalism in Former Soviet Union and Yugoslavia: The 21st century has also seen a resurgence of nationalism in countries that were previously part of the Soviet Union and Yugoslavia, as well as in other countries around the world. This has led to the rise of separatist movements and the creation of new nation-states such as South Sudan and Kosovo.

It is important to note that these developments in nationalist mindset will not happen in isolation, and will be impacted by a variety of factors such as economic conditions, political will, and technological advancements. Furthermore, the impact of these changes on the global political landscape is yet to be seen and will depend on how they are received and responded to by governments, international organisations and civil society.
Nationalism is a complex and multifaceted concept that has undergone significant changes in the 21st century. Nationalism is defined as a political ideology that emphasises the interests and culture of a particular nation, often to the exclusion of others. In the 21st century, nationalism movements and ideologies have evolved in response to changing global political and economic conditions.
One of the most significant changes in nationalism in the 21st century has been the rise of far-right and populist nationalist movements. These movements have been characterised by anti-immigrant sentiment, xenophobia, and a rejection of globalism and international cooperation. They have gained significant support in many countries in Europe and North America, and have led to the rise of leaders such as Donald Trump in the United States, Matteo Salvini in Italy, and Viktor Orban in Hungary.
Another change in nationalism in the 21st century has been the increasing use of social media and other digital platforms to spread nationalist ideologies and mobilise support. These platforms have allowed nationalist movements to bypass traditional gatekeepers such as the mainstream media and reach large audiences directly. This has led to the rise of alternative media outlets, such as Breitbart and Infowars, which have helped to spread nationalist ideologies and conspiracy theories.

The 21st century has also seen a resurgence of nationalism in countries that were previously part of the Soviet Union and Yugoslavia, as well as in other countries around the world. This has led to the rise of separatist movements and the creation of new nation states such as South Sudan and Kosovo.
The 21st century has also seen the emergence of new forms of nationalism, such as econationalism and feminist nationalism. Eco-nationalism emphasises the importance of protecting the environment and preserving the natural resources of a particular nation, while feminist nationalism focuses on the rights and interests of women within a particular nation.
Another expected change in nationalism is how it will become more intertwined with identity politics. Nationalism is expected to become more tied to issues of race, gender, sexuality, and religion, as different groups within a nation compete for power and resources. This is likely to lead to increased polarisation and division within societies, as well as the rise of new forms of identity-based nationalism.
Furthermore, the 21st century is also likely to see the rise of transnational nationalism, which emphasises the importance of shared cultural and historical ties across borders, rather than the traditional focus on a single nation-state. This form of nationalism may be seen as a response to the increasing interconnectedness of the world and the growing sense of global citizenship.
In conclusion, nationalism in the 21st century has undergone significant changes, with the rise of far-right and populist movements, the increasing use of digital platforms to spread nationalist ideologies, the resurgence of nationalism in countries that were previously part of the Soviet Union and Yugoslavia, the emergence of new forms of nationalism such as eco-nationalism and feminist nationalism, and the expected intertwining of nationalism with identity politics. It is important to note that these developments will not happen in isolation, and will be impacted by a variety of factors such as economic conditions, political will, and technological advancements.
