Doing Time as a Federal Prison: 1934-63. In 1933, the Army relinquished Alcatraz to the U.S. Justice Department, which wanted a federal prison that could house a criminal population too difficult or dangerous to be handled by other U.S. penitentiaries.
Alcatraz also housed a number of ârebelliousâ American Indians, including 19 Hopis from the Arizona Territory who were sent to the prison in 1895 following land disagreements with the federal government. The inmate population at Alcatraz continued to rise during the Spanish-American War (1898).
