Answer:
At the age of twenty-one, Harriet Beecher Stowe was an American writer and abolitionist who moved to Cincinnati, Ohio. There, she met her husband, Calvin Ellis Stowe, and became heavily influenced by the abolition movement. Since she now lived on the border of Kentucky and Ohio, she was able to witness the horrors of slavery firsthand. This exposure to slavery had a great impact on her, an experience that would lead her to write Uncle Tom's Cabin. Furthermore, when she lost her 18-month-old son, she understood how it must feel like when the children of slave mothers were sold away to other slave owners. Stowe's family and Stowe helped their servant, a runaway slave, escape through the Underground Railroad. She was Christian, so this religious point-of-view and sense of morality act as an essential backdrop in writing Uncle Tom's Cabin. Harriet's entire life consists of events and experiences that led her to write her famous anti-slavery novel, Uncle Tom's Cabin. During this time, there were many abolitionist movements. These movements may have played an essential role in influencing her. Harriet Beecher Stowe was an abolitionist who had fought for slavery, both with her words and actions.
