In recent decades, a "humanization" of international law has taken place: the protection of people (and peoples) has become an important regulatory goal. This lecture is designed to provide an overview of human rights protection regimes at the global and regional levels. After an introduction into basic questions and fundamental problems of human rights protection and an overview of universal human rights protection treaties, the lecture provides comparative insights into regional protection regimes. In addition to a discussion of procedures before judicial and quasi-judicial protection institutions, special attention will be paid to substantive human rights guarantees. Central cases will illustrate the importance of individual human rights and their enforcement. Finally, human rights protection in multi-actor constellations and in the multi-level legal system will be examined.
