Is Hedda Gabler a work of realism or naturalism, and why?

My answer would be that "Hedda Gabler" is an example of
Realistic literature.

Given that Naturalism does stem from
Realism, many texts can be justified under either period. But, here, very simple
characteristics of the play determine it as a Realistic piece. (Though some may argue my
point-of-view.)

In my interpretation, "Hedda Gabler" is a
Realistic piece based upon simple reasonings.

First, the
setting of the play is in that of an aristocratic home. In Naturalistic literature,
settings are typically that of the poor. This contradiction to Naturalistic the typical
Naturalistic setting is one reason I deem it a piece of
Realism.

Second, the characters are far from ordinary. They
newly wed couple has just returned from a six month long honeymoon. Naturalistic
characters are typically poor and can only dream of a life like the one describe by
Ibsen.

Lastly, characters in the play are able to better
their own lives. In Naturalistic literature, no matter what a character does to better
their life, they always succumb to forces beyond their control- typically forces of
nature which are stronger than the power of man.

Yes,
environmental conditions shape characters in Naturalism, but only to the degree in which
it (nature) removes free will.  Here, in the play, free will is exerted (refer to
Lovborg and his ability to overcome).
