Jane Pierce, American wife of Franklin Pierce, 15th First Lady of the United States (died 1863)

Jane Means Pierce was the first lady of the United States from 1853 to 1857, being married to Franklin Pierce, the 14th president of the United States.

Franklin Pierce was the 14th president of the United States, serving from 1853 to 1857. A northern Democrat who believed that the abolitionist movement was a fundamental threat to the nation's unity, he alienated anti-slavery groups by signing the Kansas–Nebraska Act and enforcing the Fugitive Slave Act. Conflict between North and South continued after Pierce's presidency, and, after Abraham Lincoln was elected president in 1860, the Southern states seceded, resulting in the American Civil War.

First Lady of the United States (FLOTUS) is a title typically held by the wife of the president of the United States, concurrent with the president's term in office. Although the first lady's role has never been codified or officially defined, she figures prominently in the political and social life of the United States. The first lady of the United States traditionally acts as the hostess of the White House.
