Livre d'Or

I don't think I learned about it at school either. If I did, it would probably have been in English class as background for some piece of literature, or maybe in RE class as background for Corrie ten Boom, but definitely not in History. We never studied any history more recent than the Industrial Revolution.

The people who took History as a GCSE option (all three of them) studied WWII, so I assume they studied the Holocaust (OTOH, another comment in this thread suggests it's possible to study WWII and briefly cover the Holocaust but not mention the Jews). IDK whether this was just random or a deliberate decision on the school's part to shield under-13s from the distressing topics.
