We provide a pedagogical introduction to the field of grand unification focusing the attention on proton decay and neutrino masses. Despite the huge amount of work done since the seminal paper of Georgi and Glashow, no theory of grand unification has clearly emerged so far. In this respect we emphasize the role of minimality as a guiding principle in order to discriminate among models and eventually falsify them. Sticking to the SO(10) case minimality is closely related to the complexity of the Higgs sector. We finally review some recent results on the spontaneous symmetry breaking of SO(10) GUTs.
