The Son of Denmark

Can you recognize this well known play?

My sire's death
did mar my heart.
Losing my mother
to the cause thereof
was more than I could bear.
A ghostly shadow
passing in the night
did reveal the truth
and bring to light
that which I must do.
I could not bring myself
to perform my task so true.
My love lost to madness,
which soon would come for me.
Then came the battle,
the truth revealed to all.
What was wrong was set right
as each player
faded into the night.
Blood bathed the land clean
as the curtain closed on this
our final scene.
