What is Macbeth?

I have never heard of the play "Macbeth". I have never been taught about this play. However, Ive heard lots about Shakespeare and his book last year we learned about"the midnights dream".In addition, i have also learned about "Romeo and Juliette", a famous love story about the two being separated because their families do not get along. I know Shakespeare has many well known plays and poems.I do not like learning about Shakespeare because it does not interest me.Last year my previous teacher summarized Shakespeare's history but i do not remember it anymore.
