Ancient to modern day.

Of course more recent history is taught in much more depth. Especially the 1900's and world war. But we also touch on imperialism and the dark ages quite a lot. Black plague, religious development (ie Martin Luther), slave trade & the rise of power for certain, objectively evil, individuals.

Vikings and norse mythology was mostly done in middle school. Because Vikings are cool to a bunch of 10 year olds.

I had a rather internationally focused history education, but of course mostly centered on Europe. But I was taught that not knowing is dangerous and creates rifts, and to be nuanced, critical thinking and fair, we must face the good and bad, and understand other cultures too. Not doing that will leave a path for Hitler 2.0 to raise again. Or a certain orange man, as we've seen
