Its important to note that revolutions are not all the same. Revolution is just a term to describe a sudden restructuring of society. Just as there can be a proletarian revolution that leads to a socialist society there have been bougeoise revolutions that created a capitalist society out of the old feudal societies. With the American revolution of course you have to take the fact it was a colony (not uncommon for bougoise revolutions) into account too, but its not an isolated incident. All feudal societies reach a point where a powerful merchant class has formed who will then want to reshape society for their own benefit. When monarchs and nobles resist this shift, rather than allowing it and joining this new upper class, there will tend to be a revolution.

As far as i know one of the earliest examples of a bougoise revolution is [The Dutch Republic] (https://en.m.wikipedia.org/wiki/Dutch_Republic) Well known for being brutal colonialists under their capitalist model via the Dutch India Companies - East/West. Much like how the Soviet Union will be remembered as the first socialist nation and was way ahead of its time. the Dutch really laid the groundwork for future bougeoise controlled capitalist nations.

Now some people would argue this is the natural progression of things. Feudalism leads to Capitalism which leads to Socialism. There is some observable truth in that, but like with anything there are exceptions. The Soviet Union is a great example. Socialist thought had already developed in the more capitalist nations and Lenin in his genius saw an opportunity in the monarchist Russia. Russia, without Lenin and the bolsheviks, likely would have had a bougosie revolution(Likely with fracturing and independence movements as these revolutions tended to do). Lenin though took the opportunity to instead jump in and inject the more advanced(as in one developmental level ahead) socialism as an alternative to capitalism. Co-opting these revolutionairy conditions and leapfrogging forward to socialism.

This is getting long but one last important note, just as feudalism is not the first stage of human societies development. Socialism is not the last. Likely neither is communism. We can look forward a bit, to communism for example, but at a certain point its like a peasant farmer trying to speculate about the effects of robotics on society. We simply dont know what may happen in the future to cause a major shift in society. The material conditions that people in 1000 years are going to be dealing with would be almost incomprehensible to modern humans.
