Bronte's novel is broken up into three main parts: Jane's childhood tribulations, her work as a governess, and her life as a rural teacher. If you look at the novel that way, you can surely find main events in each one that can clarify Jane's life journey. Main events are also usually centered around cause and effect situations. For example, the traumatizing effects of Jane's life with her aunt and then at her school affect her life as a governess. The choices that she makes with regards to Mr. Rochester are based on what she learned in her Christian school growing up. She could have decided to ignore the fact that her beloved was already married on their wedding day, but her upbringing, faith, and adherence to social norms affected her decisions to go off on her own and risk possible death! Luckily, she did find her cousins in the wilderness, which also opens the third part of Jane's saga. Hence, the main events in Jane Eyre would have to revolve around the three main parts of the novel.
