Why Was Lincoln's Goal During The War important?

Lincoln's goal during the Civil War was crucial as it evolved from preserving the Union to including the abolition of slavery, which helped to redefine the war's purpose. This shift not only aimed to maintain national unity but also sought to promote equality and justice, ultimately leading to the Emancipation Proclamation. By framing the conflict as a fight for freedom, Lincoln galvanized support for the Union cause, both domestically and internationally, while ensuring that the war would lead to a significant transformation in American society.
