What are some of the major accomplishments and failures of revolutionary governments?

Any detailed information you give would be greatly appreciated, and also this question is Sociology based, and thanks in advance for any help that anyone can give, thank you and god bless.

What is an accomplishment for one political perspective most often is a falure from another. For example the Castro government is viewed as a failure in the US but considered to have many accomplishments in North Korea or the Chavez government in Venezula.

How's my grade so far? Think I'll pass?
