What are the distinctive features of feudalism as a political system? how does the feudal system explain patterns of political change in postclassical europe?

Some distinctive features of feudalism as a political system include landowners having their own armies and resources, and land owners putting themselves under the protection of the large estates instead of fighting. These features would eventually lead to big estates which would then make a leader, like a king, rise above the other vassals. In other words, this meant that they went from being decentralized to centralized monarchies.

The feudal system showed that the vassals would belong to the kings, yet today we don't belong to anyone
