What was Bismarck's IQ?
Bismarck never took an IQ test, and no Cox 1926 figure appears for him in the tables we checked. LifeScore uses 140+ as an editorial marker, with a range of 130 to 150, based on unifying Germany and managing European diplomacy for two decades.
What is Realpolitik?
Realpolitik means politics based on practical results and power rather than ideology. Bismarck is its best-known practitioner. He made and broke alliances as needed, fought short wars for specific aims and introduced social insurance partly to undercut his socialist opponents.
Why was Bismarck called the Iron Chancellor?
The nickname is usually traced to his 1862 speech saying the great questions of the day would be decided not by speeches and majority votes but by iron and blood. He meant military power and industry. He then used short, limited wars to reach specific goals.
Did Bismarck create the welfare state?
He created the first national social insurance system. Health insurance came in 1883, accident insurance in 1884 and old-age and disability pensions in 1889. His motives were partly political: he wanted workers to look to the state rather than to the socialists he was trying to suppress.
