Milan Svolik of University of Illinois studied 316 dictators who held power for at least one day between 1945 and 2002. Out of those 316, 13 stepped down in an unclear way, so he ignored them. The resulting is a pretty cool table which ascertains:1. that 22% of them don't even make it till a year
2. coups d'etat hve been the most widespread way a dictator was taken down unconstitutionally, foreign intervention - least widespread
It would be interesting to see how the share of each path is changing from decade to decade...
