We gloss over most kings n queens too. Though we cover before Middle Ages. You guys not do much on the Tudors I take it? (You just mention Elizabeth, though I'm unsure if you mean
this one
or this one
)
We do quite a bit on the Tudors.
As for America:
Got discovered, colonised (We mostly sent our OTT religious folks over), We had a little bit of a skirmish, you guys made a constitution, cowboys n indians a little bit, helped in WWI n WWII, lad-i-da, modern day.
However I did 20th Century America for GCSE History, so I got a fair bit of a focus on that end of the deal:
Protectionism, Boom, Wall Street Collapse, depression, prohibition, civil rights movement, communism/cold war, JFK, Space race, Vietnam..and then end of cold war.
