The Civil War sweeps away the lifestyle in which Scarlett was raised, and Southern society falls into ruin. Scarlett, left destitute after Sherman's army marches through Georgia, becomes the sole source of strength for her family. Her character begins to harden as her relatives, the family slaves and the Wilkes family look to her for protection from homelessness and starvation. Scarlett becomes money-conscious and more materialistic in her motivation to ensure her family survives and Tara stays in her possession, while other Georgian farmers lose their homes. This extends to first offering herself as a mistress to Rhett; although after Rhett's rejection, Scarlett resorts to marrying her younger sister's beau, Frank Kennedy, investing in and starting a business herself, engaging in controversial business practices and even exploiting convict labor in order to make her lumber business profit. Her conduct results in the accidental death of Frank, and shortly after she marries Rhett Butler for "fun" and because he is very wealthy. They have a little girl named Bonnie, but she dies from a horseback riding accident that leaves Rhett and Scarlett's relationship unstable.
