The petticoat affair was a political scandal during Andrew Jackson's presidency in the early 1830s that revolved around the social ostracism of Peggy Eaton, the wife of Secretary of War John Eaton. This controversy highlighted the tensions within Jackson's administration and the role of social customs in politics, as it involved the wives of prominent politicians and their judgment of Peggy's character, ultimately leading to the resignation of several cabinet members. The event also underscored the clash between Jackson's populist ideals and the traditional values held by the Washington elite.
