 Despite these definitional worries, there is a fair amount of agreement about the classical, historically paradigmatic form of nationalism. It typically features the supremacy of the nation’s claims over other claims to individual allegiance and full sovereignty as the persistent aim of its political program. Territorial sovereignty has traditionally been seen as a defining element of state power and essential for nationhood. It was extolled in classic modern works by Hobbes, Locke, and Rousseau and is returning to center stage in the debate, though philosophers are now more skeptical (see below). Issues surrounding the control of the movement of money and people (in particular immigration) and the resource rights implied in territorial sovereignty make the topic politically central in the age of globalization and philosophically interesting for nationalists and anti-nationalists alike.
