What would make a revolution a succes?
vovikov84 [41]

Answer:

Most revolutions start because a certain group finds something unjust. For example, the French revolution basically started because the French people believed their government to be unjust. So, for a revolution to be a success would be for that particular group to change what they saw as wrong.
