Abstract
This article is based on The Sovereignty, book written in 1927 by the german philosopher and jurist Hermann Heller. It studies the concept of sovereignty in the thought of Hermann Heller in order to establish, first, a relationship between the historical context of the Weimar Republic and it’s precedent philosophical and juridical currents and, second, to contrast Heller’s concept of sovereignty with two contemporary thinkers, namely Carl Schmitt and Hans Kelsen. Thus, the author states that Hermann Heller stands between the existentialist voluntarism represented by Carl Schmitt and Hans Kelsen’s positivism, and that he has created a significant background for the current conception of sovereignty in international law.
