Content warning: 600 years so a lot of things must've happened while it was a thing. Damn, I had no idea Brazil was "discovered" while it was a thing and we became a republic not long after it ended. Plus Napoleon made Inquisition illegal in France)
I only figured this out today bc I'm playing A Plague Tale and was curious about what was happening during those years irl and did some quick Wikipedia searches
I'm glad teachers didn't make us remember "random" years, it wouldn't actually help, but it's crazy how little we relate different subjects in History with each other when teaching
I think one of my History teachers, who gave me classes in High School and some Middle School years, understood this was a problem bc in his first class every year he always drew a timeline of world events
I always loved this and wished he did it more often
My memory might not be doing great either, bc I generally remember learning about things but don't really remember details. E.g. I remember learning about the 100 years war and that it was a 116-year-long war in Europe but I remembered nothing else about it
But while this part might be my memorys fault, the general lack of intuition about simultaneity and order of events is not and was always a problem for me. I remember being confused about this and impressed at historical events timelines way back in school. One of our books had a timeline like that too (tho it was cluttered, which is understandable but made it harder to read) which I often spent a while looking at
