Nationalist forces refer to groups or movements that seek to promote the interests and culture of a specific nation or ethnic group. These forces often aim for greater autonomy, independence, or recognition of their national identity. Nationalist movements can arise in response to perceived oppression or marginalization by larger political entities. Throughout history, nationalist forces have played significant roles in various conflicts and political changes. Examples include the Indian National Congress during the struggle for India's independence and the Irish Republican Army in Ireland. These movements can vary widely in their methods, ranging from peaceful advocacy to armed resistance.
