>>510211894>He claimed a title contrary to His Emperorship.No.
He claimed the title of his mother after defeating her in battle.
His mother recieved that "title" from her own father, the grandfather of both D. Afonso Henriques and Alfonso VII, the Emperor of León.
So the title *was* already recognised by an Emperor of León, and one considered in high respect.
Eventually D. Afonso Henriques would be King, completely free from the Emperor of León, sure. But we have to wonder how.
And I will tell you:
Because the very Emepror of León decided that a huge Empire was not the best way.
That's why the Emperor of León, D. Alfonso VII himself, divided his Empire and made one of his sons King of León and the other King of Castille.
And the King of León, the most prestigious one given the Imperial claim / history, was married to one of the daughters of the Portuguese King, D. Afonso Henriques.
So it was not D. Afonso Henriques betraying the Emperor and snatching a part of the Empire from him. But it was the Emperor himself who voluntarily divided his Empire - as it was common at the time:
León to his older son.
Castille to his younger son.
Portugal to that crazy based cousino of his who ended the power of his whorish bastard aunt.
Also you can see in the battle of Badajoz, which was a huge city back then, thus highly relevant, when the Emperor of León teams with the moslems to fuck the expansion of Portugal and captures D. Afonso Henriques.
They treat D. Afonso Henriques as a friend (family really) and a great legendary Statesman. No harm or ill intention there. Although I think this might have been the next "Emperor" which would be son in law of D. Afonso Henriques...
Anyway, all this happens before the Pope recognises Portugal as independent.
You need to study History more. Especially family History (among the nobiility and royal houses) as it was how things moved back in those days.
