i read all the Harry Potter books but they never mentioned who became Headmaster after Dumbledore and Snape died... Who do u guys think became headmaster?

Minerva McGonagall coz she was assistand principal before dumbledore died.. Afterwards, J.Rowling said in an interview, that it'd be someone completely new..

Rowling said in an interview: Nineteen years after the Battle of Hogwarts, the school for witchcraft and wizardry is led por an entirely new headmaster (“McGonagall was really getting on a bit”) as well as a new Defense Against the Dark Arts teacher

I think Minerva Mcgonagall became Hogwarts' Headmistress... But that's just my opinion...

Yes,M is loyal and authoritative enought to be the headmaster after Mr.D died.
But I do hope NL will sit in the headmaster office oneday.

Seamus Finnigan!!!!..... Kidding! I've no bloody idea!!!!!!!!!!! :D

Well if the newly restored wizardry system knew what it was doing (which it does, derr! I mean, all the goodies are in it!) they would of appointed Minerva McGonogall. She was deputy headmistress before Dumbeldore died, so she was seguinte in line for the position, but the rise of Voldemort and the infiltration of the Ministry of Magic meant that the system became corrupted and Snape was given the Hogwarts topo, início spot. When Voldemort and his followers were defeated the system was set to rights and so Minerva McGonogall should of got the role. But who knows!

i heard Minerva Mcgonagall became headmistress..that's what a lot of people say in lots of HP sites..

i think McGonagal because she was the loyalest of the teachers to dumbledore apart from snape and she is mais like a headmaster kind of person.

most probably it was Minerva McGonagall. she didn't die in the last book anyway, and she was deputy headmistress while Dumbledore was alive. :)

well i hope its NOT snape i tink it might be Professer Mcgonagall.xxxxxxxxxxxxxxxxxxxxxxxxx

I think it would have been McGonagall as she was the deputy head

AHHH everyone said the same thing i was going too XD
Mcgonigall (sorry for the mispelling)
I always thought she'd be it, but I started thinking because of the 19 years later it'd be Nevil Longbottom.

After Dumbeldore and Snapee....i tinck is Minerva McGonagall.....i dont see anyone doing the jobe mais better that she dosee...:d

Hagrid hehehe:)WHY NOT?
actualy i have no idea...i don't think it is minerva

McGonogal for the good first decade after the war then I would think she'd retire. I don't know who would take over then, not Neville he's too sweet to be a headmaster; he'll back down to kids who are causing mischief (Fred and George kind of stuff). But I was thinking Percy; he did come around eventually and he really loved the school.

It's Minerva Mcgonagall, she takes a lead

I think, unless she retird or died after the battle, it might be McGonagll (I spelt it so wrong, sorry)
At first I thought Hermione might work at Hogwarts but she was at the station septembre 1, so no.

Minerva McGonagall becomes headmistress seeing as how she was the assiting head mistress when DD was there.

first it was McGonagall but when Harry's kids started going to Hogwarts there was a new principle i think J.K. said that McGonagall was getting old

Before Snape it was actually Minerva (McGonaggall) but after Voldemort took over Snape became headmaster but then when they had that big fight and Minerva took back Hogwarts she became Headmistress once again but in the epilogue of the Deathly Hallows part II J.K Rowling said that she would have retired because she would have gotten a bit older.

If I had to take a guess I would say McGonagall bc she is the most qualified to run the school...
