In which language did Anne Boleyn write letters to Henry? (Some of them seemed to be in French, but, did Henry know French?
We don't actually have Anne Boleyn's love letters to Henry, only Henry's and quite a few of them were written in French. Henry VIII knew French, Latin and Greek, and, I think, Italian, as well as his native tongue of English. The letter allegedly written by Anne from the Tower in 1536 (many people think it's a forgery) was in English.
