Why did Historia's mother hate and reject her?


Other than her being a bastard child, was any reason given as to why
Historia's mother hated her and disowned her?




The reason was that Historia is [Rod
Reiss](http://shingekinokyojin.wikia.com/wiki/Rod_Reiss)'s child. Since
Historia was his child, she has the ability to obtain the abilities of the
Coordinate and use them to the fullest. This was the reason that the Military
Police's First Interior Squad had to murder Historia and her mother in order
to ensure that power would not fall into the hands of people the central
government could not control.

Therefore, Alma hated Historia as Historia's existence would lead to her
death.

> Historia Reiss - She carried deep resentment towards her daughter, even more
> so before Kenny slit her throat, as Historia's existence is the reason she
