You might have a point. History class starts with Antiquity (sometimes with Ancient Egypt and even sone prehistory if you're lucky), so there isn't that much time to go into details and to move beyond Europe, sadly (exceptions: the USA and Colonialism). We usually don't have to memorise royal lineages, though, the emphasis is more on analysis and understanding than memorisation.
But yeah, about 2500 years of history cramped into 6 years of school - there's a lot not taught.
I've thought about how to teach history in a different way (more emphasis on everyday life and enabling the pupils to analyse texts and sources for themselves) but it's not easily done with the time constraints there are.
