How did the 21 amendment affect the 18

 Prohibition proved difficult to enforce and failed to have the intended effect of eliminating crime and other social problems–to the contrary, it led to a rise in organized crime, as the bootlegging of alcohol became an ever-more lucrative operation. In 1933, widespread public disillusionment led Congress to ratify the 21st Amendment, which repealed Prohibition.

During the middle ages, a Lord was a character of nobility. They generally had a high political standing and were rich.

The definition of a vassal, especially in the middle ages, could mean two different things. A vassal is either a piece of land that is virtually a slave to its owner, or a literal slave.

Depending on the context of this question, the relationship between Lord and vassal would either be owner/slave or landowner/subordinate land. Keep in mind, vassal is generally used with a negative connotation.
