Instrumental or cognitive aggression: these terms are interchangeable, both meaning the aggression is planned and is used as a means to meet a goal that can't be achieved in any other way.

Political Parties Splinter: The issue of slavery split the Democratic Party in two in 1860.
The Election of 1860: Slavery was the main issue and Lincoln wanted to ban it in all new territories, and since the north had a bigger population than the South Lincoln had the most votes and won.
Southern States secede: Before Lincoln took office, seven states left the Union. The Confederate States of America chose Jefferson Davis as their president, and the right to slaves was allowed in their Constitution
Efforts at Compromise Fail: When he took office, Lincoln tried to save the Union without war.
First Shots at Fort Sumter: Lincoln calls South Carolina to tell that he is going to send ships there to supply the fort.
Lincoln Calls out the Militia: Lincoln asked the Union states to provide 75,000 militiamen. Slave States who were still in the Union got mad and some left. This is where the Civil War started to kick off.
