Polk’s secretary of state before becoming president in 1857. That experience made him one of the most extensively prepared officeholders of his generation. His presidency nevertheless ended with seven southern states leaving the Union after Abraham Lincoln’s election, and with the country approaching civil war.","Buchanan’s foreign policy ambitions centered on Cuba, Mexico, and Central America. He continued efforts to acquire Cuba from Spain and sought transit privileges across routes linking the Atlantic and Pacific. Congressional opposition prevented several initiatives, including a proposed treaty granting American transit rights through Mexico. Domestic conflict increasingly limited his ability to obtain support for expansion abroad.","A dispute over San Juan Island brought American and British forces close to war in 1859. Buchanan sent General Winfield Scott to contain the confrontation. Scott and the British colonial authorities arranged the withdrawal of reinforcements and a joint military occupation pending a final boundary settlement. That restraint prevented a local dispute from becoming another war with Britain, even as Buchanan pursued more coercive policies in parts of Latin America.","Buchanan supported the Supreme Court’s Dred Scott decision and pressed for Kansas’s admission under the proslavery Lecompton Constitution, worsening divisions within the Democratic Party. After Lincoln’s election, he argued that secession was unlawful but that the federal government lacked authority to coerce a state back into the Union. His administration’s hesitation, cabinet divisions, and inability to settle control of federal installations left Lincoln to confront the crisis. Buchanan retired in March 1861, shortly before fighting began at Fort Sumter."],"id":"global:person-4cc9b01ce9cbe1d658674f17","identifiers":{},"identityScope":"global","legacyPersonIds":[],"legacyUrl":"https://chanceries.org/diplomat-faf82cb56a1c1709d5fb.html","name":"James Buchanan","notes":[],"paragraphSources":[["growth-person-4cc9b01ce9cbe1d658674f17-miller-buchanan-life-in-brief"],["growth-person-4cc9b01ce9cbe1d658674f17-miller-buchanan-foreign-affairs"],["growth-person-4cc9b01ce9cbe1d658674f17-miller-buchanan-foreign-affairs","growth-person-4cc9b01ce9cbe1d658674f17-nps-san-juan-pig-war"],["growth-person-4cc9b01ce9cbe1d658674f17-miller-buchanan-domestic-affairs"]],"profileUrl":"diplomat-faf82cb56a1c1709d5fb.html","relatedEvents":[],"relatedPeople":[],"relationships":[],"researchStatus":"reviewed","reviewedOn":"2026-11-04","revision":"89a105a1c1500bd3","sources":[{"accessedOn":"2026-11-04","date":"","id":"growth-person-4cc9b01ce9cbe1d658674f17-miller-buchanan-life-in-brief","locator":"Relevant narrative sections in the named biographical essay","publisher":"University of Virginia Miller Center","title":"James Buchanan: Life in Brief","type":"institutional","url":"https://millercenter.org/president/buchanan/life-in-brief"},{"accessedOn":"2026-11-04","date":"","id":"growth-person-4cc9b01ce9cbe1d658674f17-miller-buchanan-foreign-affairs","locator":"Relevant narrative sections in the named biographical essay","publisher":"University of Virginia Miller Center","title":"James Buchanan: Foreign Affairs","type":"institutional","url":"https://millercenter.org/president/buchanan/foreign-affairs"},{"accessedOn":"2026-11-04","date":"","id":"growth-person-4cc9b01ce9cbe1d658674f17-miller-buchanan-domestic-affairs","locator":"Relevant narrative sections in the named biographical essay","publisher":"University of Virginia Miller Center","title":"James Buchanan: Domestic Affairs","type":"institutional","url":"https://millercenter.org/president/buchanan/domestic-affairs"},{"accessedOn":"2026-11-04","date":"","id":"growth-person-4cc9b01ce9cbe1d658674f17-nps-san-juan-pig-war","locator":"1859 military escalation; Buchanan dispatches Scott; joint occupation agreement","publisher":"U.S. National Park Service","title":"The Pig War","type":"institutional","url":"https://www.nps.gov/sajh/learn/historyculture/the-pig-war.htm"}],"topics":[]},"schemaVersion":1}
