Throughout the story of Snow-White, Competition is played out in numerous ways. As the famous saying goes-only the strongest survive and to the victor go the spoils. There were a few power struggles going on even under the primary plot. This is one way to describe some of the seemingly bizarre or extreme motivations that push the story to a grisly, but happy ending.
The first queen apparently dies in childbirth (but do we really know this for sure?) and is replaced with a new queen in order to re-establish the king's dominance over his kingdom. How can his empire be complete without a queen, considering the king was now a single parent as well? His life as a widower could not last in a time when meeting the status quo was so closely tied to the validity of self. He had to have a wife if he already had a child. Quite possibly, the king was influenced by outside forces to re-marry, or simply did not want to have sole responsibility of raising Snow-White and took another wife to safe face.
The battle between Snow-White and her step-mother was demonstrated to extreme ends. It was contested from both sides. The lack of action on Show-White's part is an action in itself. Her passivity was an act of rebellion and self-preservation. I believe that Snow-White was far more manipulative than the story gives her credit for. Regardless of the initial chaos in any situation that the girl found herself in, especially those of which were instigated by the queen, Show-White never failed to emit an enigmatic seduction to lure others to act on her behalf to escape utter isolation and death. In the end, The queen simply wants to exclude Snow-White from the gaze of the mirror and take the title of "The fairest of them all." Yet SnowWhite fights just as tenaciously to be included, not only in the mirrors eyes, but her father the kings, the dwarves, and ultimately her own prince.
