This is sort of neither here nor there to Victoria ruling, but your implied contention that she was a great ruler because she was the “grandmother of Europe” really means very little in weighing her leadership skills.
Having her children was little more than biology.
She had sex.
She got pregnant.
A child was born.
By most accounts she was not an entirely great mother, however it would be somewhat unfair to judge her according to today’s standards.
And of course, no fault of Victoria’s that her grandchildren marrying introduced hemophilia to several ruling families.
One thinks of Russia and the effect that Alexandra’s obsession with Rasputin had on events there.
The revolution would have happened anyway, but perhaps they would have survived if the populace and the court itself had not been so disgusted with them.
That you fail to understand "THE GRANDMOTHER OF EUROPE" meme, proves, beyond a shadow of a doubt, that you are much wanting in knowing and understanding its implications AND the machinations which she, and she alone, put into motion, that showed what a true "leader" she was. And even before she started to play around with placing her own kids on various thrones, she tried, but failed to get a "fine Italian hand", vis-a-vis the marriage plans, for his son, of King Louis-Phillip of France.
I'm NOT judging anything at all by "today's standards". I'm stating historical facts.
OTOH, you are "judging" things by assumptions based on 1)not much knowledge 2) your own skewed opinions.
Hemophilia has less than nothing whatsoever to do with the topic at hand; that being whether or not Queen Victoria was a good leader, or simply a "tool" of Albert's.
