Over the past several decades, cosmologists have settled on a coherent picture for the evolution of our Universe. At its earliest stages the Universe was very hot, dense, and featureless, and was expanding very rapidly; today, the Universe is mostly cold and empty, but contains a rich structure of galaxies arranged in huge filaments and clusters. In this talk, I will give an overview of our understanding of the course of cosmic history, starting from when the Universe was only a few minutes old, and going right through to today.
