From Gladiator:
My name is Maximus Decimus Meridius, Commander of the Armies of the North, General of the Felix Legions, loyal servant to the true emperor, Marcus Aurelius. Father to a murdered son, husband to a murdered wife. And I will have my vengeance, in this life or the next.

From Braveheart, not really a monologue, but still great:
William Wallace: And if this is my army, why does it go?
Soldier: We didn't come here to die for them!
Second Soldier: Home, the English are too many.
William Wallace: I see a whole army of my country men, here, in defiance of tyranny. What will you do without freedom? Will you fight?
Soldier: Against that? No, we will run, and we will live.
William Wallace: Aye, fight and you may die, run, and you'll live...at least a while. And dying in your deathbeds, many years from now, wouldn't you be willing to trade all of that from this day to that, for one chance, just one chance, to come back here and tell our enemies that they may take away our lives, but they'll never take away our freeeedoooomm.
