The Department of the East was a military administrative district established by the U.S. Army several times in its history. The first was from 1853–61, the second Department of the East, from 1863 to 1873, and the last from 1877 to 1913. In January 3, 1863, the Department of the East was revived, to administer the many districts and posts created by the Civil War in New York, New Jersey and the states of New England. It became subordinate to the Military Division of the Atlantic, from 1865–66 and the Division of the Atlantic, in 1868 until this department was discontinued in 1873.
