This speech is not by Henry (any of them), it is from Shakespeare's Richard II and delivered by John of Gaunt:
This royal throne of kings, this sceptred isle,
This earth of majesty, this seat of Mars,
This other Eden, demi-paradise,
This fortress built by Nature for herself
Against infection and the hand of war,
This happy breed of men, this little world,
This precious stone set in the silver sea,
Which serves it in the office of a wall
Or as a moat defensive to a house,
Against the envy of less happier lands,-
This blessed plot, this earth, this realm, this England.
