History up until the age of 16 was a bit of a gallop, there was an awful lot to pack in. I don’t really remember learning much at junior school (ie pre-11/12 years old), though I guess I did. At senior school in the run up to GCSE (the main exams you take at 16), it was a rush through the middle ages/black death, tudors, Napoleonic Wars, a whole bunch of stuff around the Industrial Revolution and lots of complicated, associated political / legal stuff (the Corn Laws seemed to go on for weeks, and I can’t remember a damn thing about them).
The American Revolution was covered, fairly briefly, when I would have been about 14 (this was in the mid 1980s), and mainly as a forebear to the French Revolution, which we covered in depth. So we were certainly taught it, and fairly dispassionately at that. We didn’t cover the War of 1812 though - I didn’t hear of that til I was an adult. Probably because we were fighting Napoleon at the time, and that was more significant (for us).
I took history at A Level (aged 16-18), but there was very focussed - 1485-1600, covering British and European history alone. So I can tell you a lot about the Tudors, the reformation (home and in mainland Europe), the unification of Spain and the Renaissance. USA? Not so much.
