The Chiral Quark-Soliton Model of nucleons is based on two ideas: 1) the major role of spontaneous chiral symmetry breaking in hadron physics and 2) the relevance of the large number of colours limit for the real world. In these lectures I review the theoretical foundations of the model, the physics involved, and some of applications. Contents: 1. How do we know chiral symmetry is spontaneously broken? 2. Low-energy limit of QCD from instantons 2.1. Some of the results 2.2. Instanton-induced interactions 2.3. Bosonization 2.4. Chiral lagrangian 3. Properties of the chiral lagrangian 3.1. Derivative expansion and interpolation formula 3.2. The Wess-Zumino term and the baryon number 4. The nucleon 4.1. Physical motivations 4.2. Nucleon mass: a functional of the pion field 4.3. Nucleon profile 4.4. Quantum numbers of baryons 4.5. Some applications 4.6. Nucleon structure functions 5. Conclusions

Nucleon tensor form factors at large $N_{c}$
In the pion mean-field picture at large Nc, the nucleon tensor charge and anomalous tensor magnetic moment are valence dominated, while the tensor quadrupole moment is sea dominated and strongly enhanced near the chir...

Pion generalized parton distributions at zero skewness
Pion valence PDFs and vector, tensor, and scalar form factors computed from NJL-model GPDs match experiment and lattice QCD after evolution, giving charge radii 0.56, 0.63, and 0.83 fm.

Pentaquarks and Maxim V. Polyakov
A review argues that Diakonov-Petrov-Polyakov's narrow-width Theta+ pentaquark prediction remains viable, identifying N*(1685) as the antidecuplet partner and citing LEPS/DIANA data as support.

Generic framework for non-perturbative QCD in light hadrons
The instanton liquid model, with instanton size, density, and quark mass as its main inputs, is presented as a generic framework for light-hadron vacuum condensates, matrix elements, and form factors.
