What did harriet beecher stowe do that increased tensions between the north and the south?

Harriet Beecher Stowe wrote the famous book called Uncle Tom's Cabin.

This book follows the journey of a man named Uncle Tom, who happens to be a slave in America for a long period of time. During this book, it describes the harsh realities that slaves in America face on a daily basis. Harriet Beecher Stowe, an advocate of abolishing the institution of slavery, wrote this book in hopes of bringing to light the inhumane treatment of slaves in America. She succeeded in her mission.

Northerners read this book, shocked at the realities these slaves faced during this period in American history. Southerners felt that it was an inaccurate representation of life in the South. Regardless, this continued to fuel tension so much that when President Abe Lincoln met Harriet Beecher Stowe, he said "So you're the little woman who wrote the book that made this great war!" This sentence alone shows how critical this book was to the start of the Civil War.
