Nationalism significantly influences domestic policy by shaping national identity and priorities. It often promotes an agenda focused on the interests and culture of a certain national group, which can impact immigration policies, social welfare programs, and even educational systems. Nationalist sentiments can lead to policies that reinforce national unity or, conversely, marginalize minority groups. Political leaders may leverage nationalism to rally support during critical times, justifying restrictive policies in the name of national sovereignty and security. This influence can spark both division and unity within a society, depending on how inclusively or exclusively nationalism is framed.
