The Duke Blue Devils are the intercollegiate athletic teams that represent Duke University, located in Durham, North Carolina. Duke's athletics department features 27 varsity teams that all compete at the National Collegiate Athletic Association (NCAA) Division I level. The name comes from the French "les Diables Bleus" or "the Blue Devils," which was the nickname given during World War I to the Chasseurs Alpins, the French Alpine light infantry battalion. Duke joined the Southern Conference in 1929, and left in 1953 to become a founder of the Atlantic Coast Conference. History Teams for then Trinity College were known originally as the Trinity Eleven, the Blue and White or the Methodists. William H. Lander, as editor-in-chief, and Mike Bradshaw, as managing editor, of the Trinity Chronicle began the academic year 1922–23 referring to the athletic teams as the Blue Devils. The Chronicle staff continued its use and through repetition, Blue Devils eventually caught on. The Blue Devils have won 17 NCAA National Championships. The women's golf team has won seven (1999, 2002, 2005, 2006, 2007, 2014, and 2019), the men's basketball team has won five (1991, 1992, 2001, 2010, and 2015), men's lacrosse has won three (2010, 2013 and 2014), and the men's soccer (1986) and women's tennis (2009) teams have won one each.
