James Nolan Mason (born July 25, 1952) is an American National Socialist.
Mason grew up in Chillicothe, Ohio. When he was 14 years old, he began communicating with George Lincoln Rockwell's American Nazi Party and became a youth member until his 18th birthday when he was sworn into the renamed National Socialist White People's Party. In the 1970s he was involved with the National Socialist Liberation Front. He later went on to form the Universal Order.
He edited, wrote, and published a newsletter titled Siege throughout the early to mid-1980s. Its contents were edited and published by Michael Moynihan as Siege: The Collected Writings of James Mason. He advocated leaderless resistance, calling for autonomous action by individuals rather than an authoritarian hierarchical organization.
Writing from Siege was combined and published as a book, (also titled Siege) in 1992. It was first published by Storm Books with an introduced by Michael Moynihan. It was republished, with a new preface by Mason and an introduction by Ryan Schuster, in 2003 by Black Sun Publications.
On 25th July 2017, Mason relaunched Siege as an online newsletter in collaboration with Atomwaffen Division.
Universal Order is the name of a National Socialist "operational front" founded by James Mason. Growing out of the National Socialist Liberation Front, Mason founded the order in the early 1980s following the advice of Charles Manson, leader of the mass-murder cult "The Family". Not only did Manson suggest the name, but he also designed the logo used by the group, a swastika superimposed over the scales of justice.
