This carefully edited proceedings volume provides an extensive review and analysis of the work carried out over the past 20 years at the Mainz Microtron (MAMI). This research is centered on the application of Quantum Chromodynamics in the strictly nonperturbative regime at hadronic scales of about 1 fm. The book goes further to offer an outlook on the next wave research, with the forthcoming upgrade of MAMI.
