For the entire planet, prior to the last few hundred years. Religion agreed, because pedos are attracted to power and religious leaders were the most powerful.
I get that isn't explicitly encouraging it, but I've never heard of any context that in any way justifies their prophet having sex with a nine year old (not that any possibly could).
The user didn't point it out that tho. Reaching puberty is the age of consent according to the Quran and Aishas age isn't a fact like you present it as. Marriage and intercourse are two different things in islam. Idk what you mean by justifying it. It was a societal norm, not only in the arab deserts but the whole world that practised in now what's called child marriage. This is general knowledge.
There was no school or any other societal structure that kept kids separate from adult responsibilities back in the day, so comparing the age of consent now vs then( as long as just a century ago) doesn't make sense. Differentiating a man vs a boy was decided by his mastery of trade he was apprenticed in. A girl and a women, periods.
You could ask the same question about the bible which set the societal norm of this exact context. Or judaism which goes even futher to state even while things which I don't want to say cause I don't want to get banned. Do not say this is whataboutism cause it's not. The arabian peninsula was indeed heavily influenced by judaism and Christianity before Muhammad was born.
Edit: forgot to add that it's not a practise anymore except some extremist groups like the taliban and some remote places like in yemen.
What do you mean it didn't happen? That law is working it's way through the Iraqi parliament and is expected to pass because it has broad support. That's not extremist, that's just Islam within 2 standard deviation of the mean.
