Iron March was a far-right neo-fascist and neo-Nazi web forum. The site opened in 2011 and attracted neo-fascist and neo-Nazi members, including militants from organized far-right groups and members who would later go on to commit acts of terror. The forum closed in 2017. Subsequently, former users moved to alternative websites and social networking services, such as Discord. In 2019, an anonymous individual leaked the database that hosted all Iron March content.
