A brilliant, pragmatic statesman and who worked to unify Germany and was the first Chancellor of the German Empire.
He practiced Realpolitik, a pragmatic approach that is often represented as Machiavellian.
He was called the Iron Chancellor because of a speech he made saying that "The great questions of the time will not be resolved by speeches and majority decisions...but by iron and blood."

He predicted that World War I will start because of "some damned fool thing in the Balkans."

Putting his poster on your office is a great way to piss off uber liberal college students.
"A conquering army on the border will not be stopped by eloquence."

"He who has his thumb on the purse has the power."

-Otto von Bismarck

In rugby - a Bismarck yellow is when a yellow card is given for a fantastic bone-crunching tackle which is (incorrectly) deemed to be a shoulder charge.

Some would suggest that a certain incident could be deemed a yellow card based on the Bismarck criteria.

Others would suggest that the referee was bought.
Come on Mr Ref, that's a Bismarck yellow

That wasn't a yellow, but I suppose that could be a Bismarck yellow
