Invariant random subgroups in Lie groups were introduced to deal with the limit multiplicity problem. It follows from a theorem of Stück and Zimmer (relying on a result of Nevo) that in higher rank Kazhdan groups there are only the "obvious" ones arising from lattices and normal subgroups. The goal of these lectures is to explain, starting essentially from scratch, the proof of this result, with perhaps an eye towards the case of higher rank groups without property (T).
