Who is Fortinbras and what is his role in the play

In Shakespeare's Hamlet, the appearance of Hamlet's foil, Fortinbras, a man of brevity, loyalty, and bravery, provides the impetus to Hamlet's final actions. Like Hamlet, Fortinbras has had a father slain, but he immediately seeks revenge.

Fortinbras is either of two minor fictional characters from William Shakespeare's tragedy Hamlet. The more notable is a Norwegian crown prince with a few brief scenes in the play, who delivers the final lines that represent a hopeful future for the monarchy of Denmark and its subjects.
