Lincoln's March 4, 1861 inaugural address declared his administration would not initiate civil war. Speaking directly to "the Southern States," he reaffirmed, "I have no purpose, directly or indirectly to interfere with the institution of slavery in the United States where it exists. I believe I have no lawful right to do so, and I have no inclination to do so." Confederate forces seized numerous federal forts within territory claimed by the Confederacy. Efforts at compromise failed, and both sides prepared for war. The Confederates assumed that European countries were so dependent on "King Cotton" that they would intervene; none did, and none recognized the new Confederate States of America.
Hostilities began on April 12, 1861, when Confederate forces fired upon Fort Sumter. While in the Western Theater the Union made significant permanent gains, in the Eastern Theater, the battle was inconclusive in 1861–62. The autumn 1862 Confederate campaigns into Maryland and Kentucky failed, dissuading British intervention. Lincoln issued the Emancipation Proclamation, which made ending slavery a war goal. Slavery was the central source of escalating political tension in the 1850s. The Republican Party was determined to prevent any spread of slavery, and many Southern leaders had threatened secession if the Republican candidate, Lincoln, won the 1860 election. After Lincoln had won without carrying a single Southern state, many Southern whites felt that disunion had become their only option, because they thought that they were losing representation, which would hamper their ability to promote pro-slavery acts and policies.
Root Causes .
Slavery .
Contemporary actors, the Union and Confederate leadership and fighting soldiers on both sides believed that slavery caused the Civil War. Union men mainly believed the war was to emancipate the slaves. Confederates fought to protect southern society, and slavery as an integral part of it.
