Leave it to Georgetown to use the holiday season as a chance to give students a history lesson. Originally debuting in 2008, “A Civil War Christmas” was written by Pulitzer Prize-winner Paula Vogel and is currently being featured with professional casts in Chicago and New York City. Georgetown will be home to the student-run D.C. premiere. Nomadic Theatre’s new musical, which integrates various Christmas carols and Civil War ballads into the show, transports viewers back to a war-torn and beleaguered Washington, D.C. on Christmas Eve 1864. Familiar faces include Abe and Mary Todd Lincoln, Clara Barton, John Wilkes Booth and Walt Whitman, but the show also seamlessly weaves less historically known figures, such as a mother and daughter escaping from slavery.
