What was the north response to the states seceding?

The North's response to the secession of Southern states was one of shock and determination to preserve the Union. Initially, President Abraham Lincoln sought a peaceful resolution, but as tensions escalated, he called for troops to suppress the rebellion. The North viewed secession as unconstitutional and a threat to national unity, leading to the outbreak of the Civil War in April 1861. Ultimately, the North aimed to restore the Union and end slavery, which became a central focus of the conflict.
