(and yeah, napoleon, et al, but those are in the same vein - short guy runs the world, probably an interesting story there too.)
Elizabeth ruled England for 50 years and is remembered fondly for building a global empire (by the English, don't get me wrong), and she was a woman. Yes, it's all relationships, that's the point.
The strongest guy isn't in charge of the kingdom because the queen has an army.
So it’s simultaneously true that he was “only 5’6”” and false that he was short for his time.
