There are many rebellions, fewer successful rebellions, and extremely
few social revolutions. First, the relative frequencies of elite and m
ass rebellions are investigated. Because a rational choice approach fi
nds it easier to explain elite rebellions and a deprivation approach s
eems tailored to the explanation of mass rebellions, the relative freq
uencies of these two types of rebellion favor rational choice. Second,
the small number of mass rebellions is related to military issues, su
ch as loyalty and defeat in war. Although military defeat in war is ne
ither close to a necessary, nor to a sufficient condition of successfu
l rebellion, it still might multiply its likelihood. Third, it is argu
ed that the link between international rivalries and great revolutions
via ruler discouragement and rebel encouragement is compatible with a
rational choice approach. Because it is obviously so important in rev
olutions, nationalist and religious zealotry needs to be integrated in
to rational choice approaches to rebellion and revolution.
