when did the english monarchy stop speaking french
Anglo-Norman language French was the mother tongue of every English king from William the Conqueror (1066-1087) until Henry IV (1399–1413). Henry IV was the first to take the oath in English, and his son, Henry V (1413–1422), was the first to write in English. By the end of the 15th century, French became the second language of a cultivated elite.[8]
