Naum Tyufekchiev

Naum Tyufekchiev (Bulgarian: Наум Тюфекчиев, romanized as Naum Tûfekčiev), born on June 29, 1864, in Resen, in the Ottoman Empire, was a Bulgarian and Macedonian revolutionary, explosives expert, tactician, and anarchist arms dealer. He was a member and leader of the Internal Macedonian Revolutionary Organization (IMRO).

He served as both an instructor in urban guerrilla warfare, methods of terrorism, and pyrotechnics, as well as a hub for arms trade. He also took part in plots, bombings, and assassinations across the Balkans. In addition to anarchism, he advocated for the unity of Macedonians and Bulgarians, and fought for the liberation of North Macedonia from Ottoman rule.

Furthermore, he engaged in numerous collaborations with foreign revolutionary movements, such as the Armenian Revolutionary Federation (ARF), the Committee of Union and Progress (CUP), the Bulgarian Red Brotherhood and the Russian Social Democratic Labour Party (RSDLP). He shared or sold his expertise as an explosives expert and weapons to various movements, and was responsible, among other things, for establishing the first revolutionary explosives workshops in the Russian Empire.

He was assassinated by Todor Aleksandrov, the leader of the Internal Macedonian Revolutionary Organization (IMRO), as part of factional warfare within the organization, on February 25, 1916, in Sofia, Bulgaria.
