Secessionist movements are numerous and they come in all shapes and sizes. In my research I have identified 55 active secessionist movements around the world as recently as 2011. These aspiring nations exist in a variety of countries running the spectrum from repressive authoritarian regimes to advanced democracies. Many of these movements have been violent, responsible for roughly half the civil wars since 1945.
One might think that democracy should reduce secessionism by providing minority groups with greater political voice and presenting them with non-violent political options. This is partly true. The data show that violent secessionism is less likely in advanced democracies, but we do not know exactly why this is the case. Secessionists are simply less inclined to take up arms – and, indeed, to even take this option seriously – in wealthy democratic societies.
