And that's why I was only referring to European feudalism in my posts, which is also what most people think about when we say "feudalism." I'm not knowledgeable enough to comment on Indian, Chinese, Iranian, etc. empires at the time. They operated very differently than Europe. The closest analogue is Japan, but that's a whole nother can of worms.

And the reason I only mentioned European feudalism is because it was within medieval europe where bourgeoisie capitalism started to bloom. The foundations for capitalism were laid in the urban growth of medieval Europe. By the modern era (30 years war more or less), these European states had monopolized violence and enshrined private property (mostly, that's a long process). Then these European nation-states conquered the world, imposed their economic system, and eventually the whole world became divided into nation-states that operate under bourgeoisie capitalist economics. Even socialist states mostly operate under the concept of nation-states.
