Nationalism influences political movements by fostering a sense of identity and loyalty among a specific group, often promoting shared culture, language, or history. This sentiment can lead to demands for self-determination and the desire for a nation-state, impacting international relations and internal politics. While nationalism can unify populations and drive social cohesion, it may also spark conflicts with minority groups or other nations. Political movements grounded in nationalism can result in both positive social change and adverse consequences, depending on their inclusionary or exclusionary nature.
