Who is Richmond from Richard III?

As with every historical play that Shakespeare produced,
Richard III contains an array of characters, some with several
titles, and so it can be difficult to keep track of who's who in British History.
However, Richmond, the character who appears in this play, is Henry, the Earl of
Richmond, who actually becomes King Henry VII afterwards. He can be said to be the
antagonist of King Richard III, as he is from the House of Lancaster and raises an army
to find against the rule of Richard III. Although this is quite a major part of the
play, Richmond is a minor character. He acts as a foil in the play to the devilish
tyranny of his opponent. You might want to consider how the speeches that both of these
characters make in Act V scene 3 are compared and contrasted. Perhaps to seal the
goodness of his character, after his success on the battlefield, Richmond effectively
ends the War of the Roses by becoming King and marrying Elizabeth from the House of
York.
