The other two are historical facts.
By that, I hope you mean that their opposites are historical facts. As the author of several policy documents in the rebellion era (culminating in, not beginning with, the Declaration of Independence), as a party to the drafting of the Virginia constitution, as the leader of the first opposition political party in US history, and as a president who successfully doubled the size of the country, he was kinda a big deal.
As for the Civil War, the organized governments of four secessionist states felt it necessary to draft a document expressing their reasoning, all four reviewed and approved in much the same was as the Declaration of Independence, and all stating in unequivocal terms that their separation is motivated entirely by the preservation of slavery.
http://www.civilwar.org/education/history/primarysources/declarationofcauses.htmlThe "but-but-but, states rights!" crowd should pay particular attention to the position the secession declarations take on the northern states' non-enforcement of the federal Fugitive Slave Act, as that reads as an anti-anti-Federalist screed.
