The initial stage of inelastic high energy nuclear collisions is known as the Glasma, namely a configuration of strong chromo-electric and chromo-magnetic fields which develop along the flight direction of the two colliding nuclei; the evolution of these fields eventually leads to the formation of the quark-gluon plasma. In this review-style seminar I focus on the Glasma that can be produced in high energy proton-proton collisions. The main goals are the study of isotropization, of gauge invariant correlation functions that allow us to understand the building up of color domains and the string breaking of the Glasma starting from the color strings, and of the distribution of the topological charge density which might be relevant for the chiral magnetic effect.
