Crane Brinton had a theory that all revolutions had four common stages. He compared revolutions to a disease.

The first stage is the incubation stage, where symptoms are shown before the outbreak. Some things that can happen in this stage are: economic crisis, sense of government injustice, weak rulers and half-hearted “reform”, intellectual opposition, class division and antagonism, and defeat or recruitment of armed forces by revolutionaries.

The second is the moderate stage, where people try to compromise, and reform. In this stage there is a rule of moderates.

The third stage is the crisis stage, this is when violence increases, and radicals gain control. In this stage there is radicals can creat councils and dispense harsh justice.

The last stage is the recovery stage, which brings the end of the rein of terror, and a similar government forms that has been changed by the revolution. This. Stage will either end the revolution in war or peace.

but I have a question about all this: at what stage is a revolution most likely to fail?

Well I think the most logical stage would be the first and second stages because there aren’t any radicals yet. Maybe most people don’t actually see a need for a change and a revolution never really kicks into gear. Another thing that could happen is that the government does something about it during these stages before radicals start to emerge.

so basically there are four stages to a revolution including the incubation stage, the moderate stage, crisis stage, and the recovery stage. Also, I think that the best stage that the revolution is most likely to fail in are the first and second stage.
