The goal is to present the theory of the strong interaction at the lowest known level, i.e. quantum chromodynamics as a non-abelian calibration-invariant field theory with the colour as a new degree of freedom. Starting from the historical perspective and the additive quark model towards deep inelastic scattering, structure of the proton, interactions of hadrons within the parton model, to the concept of parton distribution functions and computation of elementary processes, finally to the quark confinement in hadrons, asymptotic freedom and the concept of a running coupling.
