Harvard Law School's founding is traced to the establishment of a 'law department' at Harvard in 1817. Dating the founding to the year of the creation of the law department makes Harvard Law School the oldest continuously operating law school in the United States. William & Mary Law School opened first in 1779, but it closed due to the American Civil War, reopening in 1920. The University of Maryland School of Law was chartered in 1816 but did not begin classes until 1824, and it also closed during the Civil War.
