He was leader of the banned National Bolshevik Party, which sought the violent re-establishment of the Soviet Union, until they merged with Putin’s party (apparently deciding that Putin was neo-Soviet enough for them). He was fiercely pro-war, and was killed while heading off to fight in the Donbas.
“A few weeks ago somebody killed Vladlen Tatarsky in Sankt Petersburg, today an attempt on Zakhar Prilepin in Nizhny Novgorord. If there would be a fight between Russian factions then this is how it looked like. “
