Maxim Sergeyevich Martsinkevich (Russian: Макси́м Серге́евич Марцинке́вич, 8 May 1984 – 16 September 2020), better known as Tesak (Cleaver, Hatchet, Hand Axe, Machete), was a Russian neo-Nazi activist, media personality, vlogger, and the leader and co-founder of the Restruct movement which manifested in post-Soviet countries.
Tesak first gained public attention as a white power skinhead and the leader of the far-right youth group Format 18, which has been described as the "armed wing" of the National Socialist Society. There are numerous branches within Martsinkevich's Restruct movement, the most prominent of which is Occupy Pedophilia, stating that its goals are fighting pedophiles and spreading National Socialist views among youth. Tesak's violent approach and targeting of gay males have been criticized, although his actions have led to the imprisonment of a highly ranked official within the Russian judicial system.
Martsinkevich received three prison sentences for inciting racial or ethnic hatred. Tesak was first indicted in 2007, after disrupting political debates by performing the Nazi salute and yelling "Sieg Heil!" at a book club in Moscow. In 2009, he was sentenced to three years for making a video with racist content. Martsinkevich's memories from this time in prison are expressed through his book Restruct. Following his release from prison, Tesak was unemployed, posted vlogs, and made a living by charging others for joining his "hunts for pedophiles" and for attending his lectures on life in prison, ways of shoplifting, as well as other subjects. In the autumn of 2013, Tesak was indicted again for releasing new videos featuring racist remarks. As a result, on 15 August 2014, he was sentenced to five years in prison. On 11 November 2014, the court reduced the sentence to two years and 10 months.
On 27 June 2017, the Babushkinsky district court of Moscow sentenced Martsinkevich to ten years in a strict regimen corrective labor colony for his involvement in attacks targeting synthetic cannabinoids dealers. He died in prison on 16 September 2020.
On 16 September 2020, Martsinkevich was found dead in a pre-trial detention centre, reportedly from suicide. There were wounds on his neck that he could not inflict on himself. There are earplugs in his ears, indicating that he was attacked while sleeping.Investigators launched a preliminary inquiry into his death. He had been due to travel to Moscow for questioning as part of a criminal case dating back to 1999. He was 36.
