French client republic

During its occupation of neighboring parts of Europe during the French Revolutionary Wars, France established republican regimes in these territories. The French Republic claimed to support the spread of the republican principles in Europe, but most of these client republics, or sister republics, were in fact a means of controlling the occupied lands through a mix of French and local control.
