What did the vassals do?

Answer:

1st Answer

Anything the king wanted.  

2nd Answer

The vassals were in a relationship of mutual obligation with their superior lords or kings. They provided an oath of allegiance and support in exchange for land, which would be farmed by serfs, and from which they could gain their wealth, and protection from the lord or king. The support included keeping men ready to fight for the lord in any conflict that came along.
