Societas Domi Pacificae, colloquially known as The Pacifica House or SDP, is a secret society based at Brown University, in Providence, Rhode Island, and is the oldest student secret society in the United States. Organized in 1824 as The Franklin Society, it was created in a year when such a large class entered Brown University that the two existing literary debating societies, the Philermenian Society and the United Brothers Society could not accommodate the new students. Notable personages such as Thomas Jefferson, John Quincy Adams, and Henry Clay accepted honorary membership into the society during this time. The society was founded with the motto: Scientia Potentia Est, meaning “Knowledge is Power.”
