@user unknown is of course correct, "its" is the translation to "ihren" here, but there is more to it:
English uses the neutral "it" as a pronoun for everything not human (with a few exceptions like ships). Therefore "history" - "its".
This is not the case in German, however. German always uses the pronoun according to the grammatical gender of the noun. It is "die Geschichte" and hence "Geschichte" is feminine. Therefore the proper pronoun is "ihr" (her).
In English one would say:
Here is a dog. It barks.
In German this would be:
Hier ist ein Hund. Er bellt.
The reason is that "Hund" is masculine: "der Hund". If you want to state that the dog is female use "Hündin" (=bitch) - and the appropriate female pronoun:
Hier ist eine Hündin. Sie bellt.
I will spare you an in-depth discussion about the german "Kategoriebegriff" and its meaning for the gender-discussion at this point. Only so much: "der Hund" means either a male dog OR any dog of indefinite/unknown gender - a category. A lack of knowing this can be made up for, though, by any number of special characters along with some dozens of alternative endings affixed to the noun.
