A heads up - Multiple choice question #15 in the U1 test for Dialectic seems to be wrong to us. As far as I can tell, Stalin was dictator of the Soviet Union from 1929 to 1953, a period of 24 years, but the question asks who was dictator for more than thirty years. Teachers, you may want to mark your students' tests to reflect this. BTW, the other choices are Nicholas II, who was a czar, not a dictator (he reigned for 23 years), Alexei Brusilov (not Alexi), was a Russian general, and Lenin ruled as dictator from 1917 to 1924, 7 years.
