I will present some recent results on ergodicity breaking in many-body spin systems, both classical and quantum.

In the first part I will discuss some exact results on Stark many-body localisation as well as discuss the existence or otherwise of spatiotemporal order in its presence.

In the second part, I will focus on a classical, clean (non-disordered) system of Heisenberg spins with kinetically constrained dynamics. The character of the dynamics depends on the strength of the constraint, which drives a transition between a chaotic regime and a localised regime in which dynamics ceases. This transition is in the directed percolation universality class.
