Cosmological N-body simulations have been a central tool of large-scale structure cosmology for a long time, providing a bridge between fundamental theory and the complex structures we observe in the Universe. In this talk, I will give an overview of the theoretical foundations of N-body methods and briefly trace the historical development of the field, highlighting key milestones such as the first simulations of gravitational clustering, the emergence of cold dark matter models, and the scaling of computational methods to ever larger volumes and finer resolutions, as well as parallel attempts to improve the modelling of the Vlasov-Poisson system in terms of accuracy. I will conclude with a perspective on current challenges and the role of N-body simulations in the next generation of cosmological surveys.
