Background: James Buchanan Jr. was born in a log cabin in Cove Gap, Pennsylvania (now Buchanan's Birthplace State Park), in Franklin County, on April 23, 1791, to James Buchanan, Sr. (1761-1821), a businessman, merchant, and farmer, and Elizabeth Speer, an educated woman (1767-1833). His parents were both of Ulster Scottish descent, the father having emigrated from Milford, County Donegal, Ireland, in 1783. One of eleven siblings, Buchanan was the oldest child in the family to survive infancy.
Context: In March 1860, the House created the Covode Committee to investigate the administration for evidence of offenses, some impeachable, such as bribery and extortion of representatives in exchange for their votes. The committee, with three Republicans and two Democrats, was accused by Buchanan's supporters of being nakedly partisan; they also charged its chairman, Republican Rep. John Covode, with acting on a personal grudge (since the president had vetoed a bill that was fashioned as a land grant for new agricultural colleges, but was designed to benefit Covode's railroad company). However, the Democratic committee members, as well as Democratic witnesses, were equally enthusiastic in their pursuit of Buchanan, and as pointed in their condemnations, as the Republicans.  The committee was unable to establish grounds for impeaching Buchanan; however, the majority report issued on June 17 exposed corruption and abuse of power among members of his cabinet, as well as allegations (if not impeachable evidence) from the Republican members of the Committee, that Buchanan had attempted to bribe members of Congress in connection with the Lecompton constitution. (The Democratic report, issued separately the same day, pointed out that evidence was scarce, but did not refute the allegations; one of the Democratic members, Rep. James Robinson, stated publicly that he agreed with the Republican report even though he did not sign it.)  Buchanan claimed to have "passed triumphantly through this ordeal" with complete vindication. Nonetheless, Republican operatives distributed thousands of copies of the Covode Committee report throughout the nation as campaign material in that year's presidential election.  The Civil War erupted within two months of Buchanan's retirement. He supported the United States, writing to former colleagues that "the assault upon Sumter was the commencement of war by the Confederate states, and no alternative was left but to prosecute it with vigor on our part". He also wrote a letter to his fellow Pennsylvania Democrats, urging them to "join the many thousands of brave & patriotic volunteers who are already in the field".  Buchanan spent most of his remaining years defending himself from public blame for the Civil War, which was even referred to by some as "Buchanan's War". He began receiving angry and threatening letters daily, and stores displayed Buchanan's likeness with the eyes inked red, a noose drawn around his neck and the word "TRAITOR" written across his forehead. The Senate proposed a resolution of condemnation which ultimately failed, and newspapers accused him of colluding with the Confederacy. His former cabinet members, five of whom had been given jobs in the Lincoln administration, refused to defend Buchanan publicly.  Initially so disturbed by the attacks that he fell ill and depressed, Buchanan finally began defending himself in October 1862, in an exchange of letters between himself and Winfield Scott that was published in the National Intelligencer newspaper. He soon began writing his fullest public defense, in the form of his memoir Mr. Buchanan's Administration on the Eve of Rebellion, which was published in 1866.  Buchanan caught a cold in May 1868, which quickly worsened due to his advanced age. He died on June 1, 1868, from respiratory failure at the age of 77 at his home at Wheatland and was interred in Woodward Hill Cemetery in Lancaster.  In the northern anti-slavery idiom of his day, Buchanan was often considered a "doughface", a northern man with southern principles." Historian Kenneth Stampp wrote: "Shortly after his election, he assured a southern Senator that the 'great object' of his administration would be 'to arrest, if possible, the agitation of the Slavery question in the North and to destroy sectional parties. Buchanan was irked that the abolitionists, in his view, were preventing the solution to the slavery problem. He stated, "Before [the abolitionists] commenced this agitation, a very large and growing party existed in several of the slave states in favor of the gradual abolition of slavery; and now not a voice is heard there in support of such a measure. The abolitionists have postponed the emancipation of the slaves in three or four states for at least half a century." In deference to the intentions of the typical slaveholder, he was quick to provide the benefit of much doubt. In his third annual message, Buchanan claimed that the slaves were "treated with kindness and humanity.... Both the philanthropy and the self-interest of the master have combined to produce this humane result."  Buchanan considered the essence of good self-government to be founded on restraint. The constitution he considered to be "...restraints, imposed not by arbitrary authority, but by the people upon themselves and their representatives.... In an enlarged view, the people's interests may seem identical, but "to the eye of local and sectional prejudice, they always appear to be conflicting ... and the jealousies that will perpetually arise can be repressed only by the mutual forbearance which pervades the constitution." Regarding slavery and the Constitution, he stated, "Although in Pennsylvania we are all opposed to slavery in the abstract, we can never violate the constitutional compact we have with our sister states. Their rights will be held sacred by us. Under the constitution it is their own question; and there let it remain."  One of the greatest issues of the day was tariffs. Buchanan condemned both free trade and prohibitive tariffs, since either would benefit one section of the country to the detriment of the other. As the senator from Pennsylvania, he said: "I am viewed as the strongest advocate of protection in other states, whilst I am denounced as its enemy in Pennsylvania."  Buchanan, like many of his time, was torn between his desire to expand the country for the benefit of all and his insistence on guaranteeing to the people settling the expanded areas their rights, including slavery. On territorial expansion, he said, "What, sir? Prevent the people from crossing the Rocky Mountains? You might just as well command the Niagara not to flow. We must fulfill our destiny." On the resulting spread of slavery, through unconditional expansion, he stated: "I feel a strong repugnance by any act of mine to extend the present limits of the Union over a new slave-holding territory." For instance, he hoped the acquisition of Texas would "be the means of limiting, not enlarging, the dominion of slavery".
