Someone Help me I am in 2 years advanced classes and I need like a really good explanation of a feudal system. Of japan and Europe. Also is this picture a feudal system if not what is it.

I might be able to help

Explanation:

The feudal system was basically where the king owned everything. The king was the main head of power and he controlled all the land. There was also levels of the feudal system rankings.

Basically its:

-king

-nobles

-vassals

- and the poor/peasants

Now to get land, you would have to serve the king.  Even then the land would still not be yours truly.  Basically the person you are pledged to is the rank higher than you.

so the other answer can get brainliest
