Since the advent of SN 1987A, considerable progress has been made in our understanding of type II supernova explosions. It is now realized that they are intrinsically multidimensional in nature due to various hydrodynamical instabilities which take place at almost all stages of the explosion. These instabilities not only modify the observables, but are also thought to be at the heart of the supernova mechanism itself, in a way which provides robust and self-regulated explosions. I review these instabilities placing them into their appropriate context and identifying their role in the genesis of core-collapse supernovae.
