Causes of the Civil War: Slavery and Control of the Government. Throughout the first half of the 19th century, Southern politicians sought to defend slavery by retaining control of the federal government.
The Civil War was not entirely caused by Lincolnâs election, but the election was one of the primary reasons the war broke out the following year. Lincolnâs decision to fight rather than to let the Southern states secede was not based on his feelings towards slavery. Rather, he felt it was his sacred duty as President of the United States to preserve the Union at all costs.
