In Lecture 1, I survey the thermodynamics based on quantum chromodynamics as the fundamental theory of strong interaction physics. In particular, color deconfinement and chiral symmetry restoration are elaborated. In Lecture 2, the phase diagram of strongly interacting matter is presented and interpreted in terms of hadronic interaction regimes. For the deconfined region, the possibility of a novel phase consisting of massive quarks is considered. In Lecture 3, the spectral analysis of the quark-gluon plasma through quarkonium dissociation is presented. It is subsequently applied to the question of QGP formation in high energy nuclear collisions. In Lecture 4, the relative abundance of hadron species in high energy collisions is interpreted in terms of statistical hadronization. The origin of this phenomenon is then discussed on the basis of Hawking-Unruh radiation in QCD.
