William Shakespeare is called The Bard of Avon, because he is considered to be the greatest poet that ever lived. The word "bard" means poet. Bards were traveling poets in medieval times, who made a living performing and telling stories. Shakespeare's plays were and are grouped into three categories:

Comedies: Midsummer Nights Dream, Much Ado About Nothing, and As You Like It.

Tragedies: Romeo and Juliet, Othello, Macbeth, and Hamlet.

Histories: Richard III, Henry IV, Henry V, and Henry VI.

One thing that set him apart from other playwrights was the way he would combine parts of all three categories, so his tragedies would have comic relief and comedies would have some serious parts. This was something that had not been done at his level before that time. Part of the genius that is Shakespeare was the fact that his work appealed to everyone, from kings to peasants. More than 400 years have passed since his birth, and his plays are still being read and performed all over the world.

He was a man from an unremarkable family who created an unforgettable legacy.
