Is a nation defined by shared blood or by shared commitment to its institutions?

In short: Civic nationalism posits that membership in a nation is defined by adherence to shared values and institutions rather than ethnic descent. This framework, which contrasts sharply with ethnic nationalism, suggests that a country is a political project—a daily referendum on the will to live together—rather than a biological inheritance.

The distinction between civic and ethnic nationalism was formalized by theorist Hans Kohn in his 1944 work, The Idea of Nationalism. While ethnic nationalism prioritizes common ancestry and descent, civic nationalism is rooted in the traditions of liberalism and rationalism. In this view, a nation is constituted by its constitution and political principles. Membership is theoretically open to anyone who pledges to uphold these shared values, regardless of their cultural or ethnic background.

Proponents argue that civic nationalism is essential for modern democratic governance, acting as a bulwark against racism and authoritarianism. Figures like Ernest Renan famously described the nation as a 'daily referendum,' emphasizing that national identity is a voluntary, ongoing choice. This ideology has influenced the development of representative democracy in nations like the United States and France, and it remains a core tenet for various contemporary political movements, such as the Scottish National Party, which advocates for sovereignty based on civic inclusion rather than ethnic homogeneity.

However, the concept is not without its critics. Some scholars, such as Umut Özkırımlı, argue that even 'civic' nations can exhibit intolerance, noting that historical examples like French Jacobinism utilized methods later adopted by fascists. Others contend that civic nationalism may still rely on an underlying ethnic concept, as abstract values struggle to create a sense of belonging without a specific cultural or geographic anchor. Ultimately, the debate highlights a fundamental tension in modern politics: whether a state's unity is best preserved through the rigid uniformity of a single culture or through the deliberate, inclusive embrace of diversity within a shared constitutional framework.
