"The Alabama Democratic convention its delegates to walk out of the national convention if the party refused to adopt a platform pledging a federal slave code for the territories. Other lower-South Democratic organizations followed suit. In February, Jefferson Davis presented the substance of southern demands to the Senate in resolutions affirming that neither Congress nor a territorial legislature could impair the constitutional right of any citizen of the United States to take his slave property into the common territories."

“Southern political leaders were threatening to take their states out of the Union if a Republican president was elected on a platform restricting slavery.”

“To a good many southerners the events of 1861–1865 have been known as 'The War of Northern Aggression'. Never mind that the South took the initiative by seceding in defiance of an election of a president by a constitutional majority. Never mind that the Confederacy started the war by firing on the American flag. These were seen as preemptive acts of defense against northern aggression.”

“Scorned and ridiculed by many critics during his presidency, Lincoln became a martyr and almost a saint after his death. His words and deeds lived after him, and will be revered as long as there is a United States. Indeed, it seems quite likely that without his determined leadership the United States would have ceased to be.”

“People are going to dislike you if you make a decision, even if it turns out to be the right one.”

“The great crisis facing the country was the rebellion and anybody in the North who wanted to preserve the Union now found the principal enemy to be those Southern slave owners who had broken up the country. The institution which sustained them and the institution they went to war to defend was slavery. And more and more northerners became convinced of that. As a consequence, a lot of them went the whole way over, from being conservative, pro-Southern, pro-slavery Democrats to becoming radical Republicans. Benjamin Butler is a good example, and Edwin M. Stanton is another one.”

“By the time of the Gettysburg Address, in November 1863, the North was fighting for a 'new birth of freedom' to transform the Constitution written by the founding fathers, under which the United States had become the world's largest slaveholding country, into a charter of emancipation for a republic where, as the northern version of 'The Battle Cry of Freedom' put it, 'Not a man shall be a slave'.”
