I agree completely with James1941. I remember history in US schools as an unending beginning each year about the "navigators" and the colonists who came to the Americas from Europe.
Because I grew up in a less PC invirornment and part of the century, we didn't study Native Americans at all. We usually got past Prince Henry the Navigator and Magellan and into the colonization of America.
We rarely made it past the US Civil War. Then next year, we world begin again. Even in high school when we were required to take US History to graduate, we would begin again with the navigators and never made it past the Civil War. I know from my son's education that now, they must take two years of US History and it is supposed to cover events after the Civil War. And it did in his case as he asked me who Black Jack Pershing was. I believe I remember him asking about Hitler, too.
As for Russia, I learned only about it in Geography. We learned about the steppes, etc.
Of course we learned about Seward's Folly or the purchase of Alaska from Alexander II, but the Tsar was barely mentioned.
The only time I remember hearing about Nicholas & Alexandra was in, believe it or not, what was called Ancient History (now World Civilizations I) in which we covered the Greeks and Romans. The reason that we heard about it is that I took that class in 1964 when Anna Anderson was having her case heard in Berlin and our teacher taked about it as "current events". (Imagine that all of you youngsters

)
But that was enough to get me hooked and the first book I read was
The Last Granduchess byVorres. At that time it was brand new to our library.
Even though I was living through the "Cold War" and the threat of nulcear destruction and the "Red Scare" had happened in the 1950s, I never learned anything about the Soviet Union or Russia in my schools.
In fact, I am ashamed to admit that I confused Prussia and Russia quite often and didn't even understand the concept that Russia was no more and that the Soviet Union was now.
But that stopped in a hurry after my thoughtful teacher and Ian Vorres got me hooked. I think my second book was
Once A Grand Duke by, of course, "Sandro".
To me Robert Masse was a "Johnny come lately".
