Did they retain their titles ?
Some never remarried, like Elisabeth of Roumania, queen of Greece.
Were there two emperesses at the same time, Joséphine and Marie-Louise ?
M-L later was better known as Duchess of Parma, not anymore as Emperess of France.
And she remarried twice after her divorce.
always a queen, seems to be the principle. I just realized a factual error in an earlier post: Great Britain, 1714-1718, did have a queen. It's just that Mary of Modena was the exiled widow of a deposed king who had died in 1701, the same year Parliament passed the fateful Act of Settlement.
Anyhow, my question is: HAS any woman actually been stripped of her queenly title, assuming that she even was styled with it, in the first place (I'm excluding morganatic wives from the discussion)?
The reason for my asking is that I've come to a general understanding is that a queen retains her status as such, even if she were a widow who remarried after the death of her king husband. However, I believe that there may have been an exception: I never did get a clear idea about Princess Augusta Viktoria of Hohenzollern-Sigmaringen, who married (as her first husband) the deposed King Manoel of Portugal.
