A rentier state is a regimes that depend on the collection of economic rents in the form of revenues from non-renewable natural resources, exploitation of tourism, economic aid from other states and corruption. Such regimes are much freer to be authoritarian because they do not rely on taxation levied on their citizens. Saudi Arabia, which depends on oil revenues and the spending of religious pilgrims to Mecca, is a classic and perhaps the ultimate rentier state.
