Petticoat affair

The Petticoat affair (also known as the Eaton affair) was an 1829–1831 U.S. scandal involving members of President Andrew Jackson's Cabinet and their wives. Led by Floride Calhoun, wife of Vice President John C. Calhoun, these women (the "petticoats") socially ostracized John Eaton, the Secretary of War, and his wife Peggy over disapproval of the circumstances surrounding their marriage and what they considered her failure to meet the moral standards of a cabinet wife. The affair shook up the Jackson administration and led to the resignation of all but one cabinet member. It facilitated Martin Van Buren's rise to the presidency and was, in part, responsible for Calhoun's transformation from a national political figure with presidential aspirations into a sectional leader of the slave-holding Southern states.

Margaret "Peggy" O'Neill was the daughter of William O'Neill, owner of The Franklin House, a boarding house and bar in Washington, D.C. which was only a short distance from the presidential mansion, making it a popular social center for politicians and military officials. Margaret was well-educated; she studied French and was known for her ability to play the piano.William T. Barry, who later served as Postmaster General, wrote "of a charming little girl... who very frequently plays the piano, and entertains us with agreeable songs." As a young girl, her reputation was already under scrutiny because she worked in a bar frequented by men and casually bantered with the boardinghouse clientele. An elderly Margaret reminisced that, "While I was still in pantalets and rolling hoops with other girls I had the attention of men, young and old, enough to turn a girl's head."
