They call it American Revolutionary War, because that is what it was to them. And from their point of view it was part of bigger conflict.

They were still in mids of the aftermath of 9 year campaing in India and at europes end France joined to the war at 1778 and Spain 1779 and Netherlands 1780.

During those times they were fighting on the Caribian, Gibraltar and the open sea.

Understantably for the Americans the independence war was the big thing, but from the British side it was part of bigger conflict.

we didn't really learn about it in high school. from memory we did the Tudors, the Stewarts, the Romans, Boudica, the Egyptians, Great Fire of London, Norman invasion, the black Plague, WW1, WW2, Iron Age, Bronze Age, Renaissance, The Enlightenment.

edit: plus the Raj

and we do some on the slave trade and America is mentioned but not the main character and civil rights/suffrage which does mention more American stuff (Rosa parks, MLK)

tbf that's much more reasonable.
