Answer:
Dan Cooper is the pseudonym of an unidentified man who hijacked a Boeing 727 aircraft in United States airspace between Portland and Seattle on the afternoon of November 24, 1971. The man purchased his airline ticket using the alias Dan Cooper but, because of a news miscommunication, became known in popular lore as D. B. Cooper. He extorted $200,000 in ransom and parachuted to an uncertain fate. Despite an extensive manhunt and protracted FBI investigation, the perpetrator has never been located or identified.

Several different states had threatened secession in the first decades of the history of the United States, but it was only with South Carolina's secession from the Union on December 20, 1860 that the possibility became a reality. Lincoln was completely against secession because, as mentioned in his House Divided Speech, "A house divided against itself cannot stand, I believe this government cannot endure, permanently, half slave and half free." Lincolns goal in this speech was to differentiate himself from Stephen Douglas by saying that the united states cannot exist divided, it must either be all slave or all free. Obviously Lincoln was pushing for all free, however he wanted a gradual emancipation of the slaves.</span>
