John Cabell Breckinridge was born on January 16, 1821, at Thorn Hill, his family's estate near Lexington, Kentucky. He was the fourth of six children and the only son of Joseph Cabell Breckinridge and Mary Clay Breckinridge, members of a family that had woven itself deeply into the political and legal fabric of Kentucky and the broader American republic. His mother was a daughter of Samuel Stanhope Smith, the founder of Hampden-Sydney College in 1775, and his family name carried weight across generations of public service. Breckinridge was educated at Centre College in Kentucky, then at the College of New Jersey — later Princeton University — and finally read law at Transylvania University in Lexington before being admitted to the Kentucky bar. He served briefly as a noncombatant officer during the Mexican-American War, an experience that introduced him to the military culture that would later define a different chapter of his life.
His entry into politics came with his election to the Kentucky House of Representatives in 1849, where he took a consistently pro-slavery position in keeping with the prevailing view of his state's planter class. Two years later, in 1851, he won election to the United States House of Representatives, where he allied himself with Stephen A. Douglas and supported the controversial Kansas-Nebraska Act, which proposed opening those territories to the possibility of slavery through the principle of popular sovereignty. Following the reapportionment of 1854, which made his district's boundaries unfavorable to his re-election, Breckinridge chose not to run again. He had attracted enough national attention, however, to be placed on the 1856 Democratic National Convention's presidential ticket as the vice-presidential nominee, selected to balance the ticket headed by James Buchanan. The Democrats won the election.
Taking office at the age of 36, Breckinridge became the youngest vice president in United States history — a record he holds to this day. His tenure as vice president was marked by institutional constraints. As presiding officer of the Senate, he could not participate in the debates that raged over the deepening sectional crisis, and he found himself with little influence over President Buchanan's inner circle. He did join Buchanan in supporting the proslavery Lecompton Constitution for Kansas, a document that reflected the wishes of pro-slavery settlers but was widely regarded as fraudulently adopted. This alignment accelerated the fracturing of the Democratic Party along sectional lines.
In 1859, while still vice president, Breckinridge was elected to succeed Senator John J. Crittenden, positioning himself to move from the vice presidency directly to a Senate seat. The Democratic Party's internal divisions exploded into the open at the 1860 Democratic National Convention, when Southern delegates walked out over the platform. The party's northern and southern wings held rival conventions in Baltimore, nominating Stephen Douglas and Breckinridge respectively for the presidency. A third candidacy, that of John Bell on the Constitutional Union ticket, further divided the anti-Republican vote. The result was exactly what the fractured opposition had made inevitable: Abraham Lincoln won the election by carrying virtually all of the Northern electoral votes, while Breckinridge carried most of the Southern states. The election of 1860 demonstrated with mathematical clarity that the political mechanisms for resolving the slavery question had broken down entirely.
Taking his Senate seat as the secession crisis erupted, Breckinridge worked actively to promote compromise and preserve the Union. His state of Kentucky was deeply divided, with Unionist forces in control of the state legislature. As Confederate armies moved into Kentucky in late 1861, the political situation became untenable for men of his position. Breckinridge fled behind Confederate lines and was commissioned a brigadier general in the Confederate Army. The Senate expelled him in absentia, condemning him as a traitor. He had crossed a line from which there was no returning.
His military career proved genuinely distinguished. Following the Battle of Shiloh in April 1862 — where his corps fought in the bloody second day — Breckinridge was promoted to major general. He was assigned to the Army of Mississippi under General Braxton Bragg, a difficult association, as Bragg was a contentious commander prone to blaming subordinates for his own failures. Bragg charged that Breckinridge's drunkenness had contributed to Confederate defeats at Stones River and Missionary Ridge, accusations that Breckinridge and many other officers bitterly contested. Breckinridge joined the chorus of high-ranking officers calling for Bragg's removal. The resulting friction led to his transfer to the Trans-Allegheny Department in the Shenandoah Valley region, a posting that would produce his most significant military achievement.
In May 1864, commanding Confederate forces in the Shenandoah Valley, Breckinridge won the Battle of New Market against Union forces under Franz Sigel. The engagement was notable for the prominent role played by cadets from the Virginia Military Institute, who were incorporated into the Confederate line and suffered substantial casualties. The victory secured the valley's vital agricultural resources for the Confederacy for several more months and made Breckinridge a celebrated figure in the Confederate South. He subsequently participated in Jubal Early's campaigns in the Shenandoah Valley, including the audacious raid that brought Confederate forces to the outskirts of Washington in July 1864. Later he was charged with defending supply lines in Tennessee and Virginia as the Confederacy's strategic situation collapsed.
In February 1865, Confederate President Jefferson Davis appointed Breckinridge Secretary of War — the last man to hold that office. In that role, Breckinridge reached a clear-eyed conclusion that the Confederate cause was hopeless and urged Davis to arrange a national surrender that would preserve as many lives and as much institutional order as possible. After the fall of Richmond in April 1865, he worked to ensure that Confederate records were preserved rather than destroyed. He then made a remarkable escape from the country, eventually making his way through Florida, Cuba, and Europe before settling in Canada. He spent over three years in exile, unwilling to return to a country where he faced potential prosecution.
When President Andrew Johnson extended amnesty to all former Confederates in 1868, Breckinridge returned to Kentucky. Friends and admirers encouraged him to resume his political career — he was still relatively young and possessed a formidable reputation — but he declined, unwilling to re-enter a political arena that he believed would only deepen the country's divisions. The years of campaign and exile had taken a severe toll on his health. He died on May 17, 1875, at the age of fifty-four. He remains one of the most fascinating and contradictory figures in American political history: a young man who rose to the second-highest office in the republic, a reluctant secessionist, a capable Confederate general who recognized his side's defeat before most of his colleagues, and a statesman who chose private life over further political ambition when both were still available to him.
