I will present the recent results in the ongoing research program on approach to equilibrium. Having reviewed the basics of quantum spin systems, I will discuss the following topics:

1. Equilibrium steady states (ESS), constants of motion, and approach to thermal equilibrium.
2. Dynamical conservation laws via the Lieb-Robinson bound
3. Application of our theory to the mixed-field Ising chain, link to the ongoing research program on nonintegrable systems by Shiraishi et al.
4. Variational characterization of ESS, approach to constrained equilibrium
