Answer:
“The great questions of our time will not be settled by resolutions and by majority votes—that was the mistake of 1848 and 1849—but by blood and iron.”
Explanation:
Otto Von Bismark was also called Iron chancellor because of the stress he laid on the military advancement for the unification of Germany. He made a speech on 30 September 1882 which became his most remarkable speech and it was named 'Blood and Iron Speech', holding the last words of the speech.
