Generalissimo
From Tardis Wiki, the free Doctor Who reference
Generalissimo was a very high-ranking military title.
Hortense became the Generalissimo, and effective leader, of the People's Republic of Goritania after the monarchy of Goritania was overthrown, six months after Hortense had been named a General. Hortense was previously Queen Donna Noble's maid. (AUDIO: Death and the Queen)
