The notion of constitutional identity is a recent and enigmatic notion in constitutional law and theory. This Article demonstrates that constitutional identity—understood as a certain constitution-related self-identity of a nation or people—can be constructed from the text of a constitution, its interpretation and its application. However, constitutional identity is nothing more and nothing less than a constructed reality that can be regarded as a constitutional state's restless soul. It exists only as a constructed, simplified, imagined reality that will most likely also be contested and subject to change. Constitutional identity and the reliance on it in particular by national courts should therefore not be regarded as something sacred and absolute that can be compared to an imagined stable heart. Instead, constitutional identity should be treated with caution.
