1919-19 is correct
I did not count the Nazis as revolution, I would rather consider it a..uh what do you call a "Putsch"? Or the Term "Machtergreifung" is usually used (only referring to the rise of the nazis, means as much as uh.."grip for power"
And the French revolution..that was more than 200 years ago *g* (ok the effects you named are not, but its not what I am looking for)
clue: you got the middle one. one happend earlier, one later
