Forgive my ignorance but I come from NZ and we only have a couple of centuries of history to deal with.
My eldest is in year 5 and is doing the Tudors this year. She's come home talking about different kings and queens and princes and dukes and keeps asking me questions about who is related to who and how. I'm helping her find the answers and tbh she seems to have a good grasp on it all but how much are they expected to know.
The sort of thing she's talking about seems quite involved but it's probably just because I'm hearing it all for the first time!
