Revolutionary Konstantin Nunkov

Konstantin (Kosta) Nunkov, known by the pseudonyms David and Ognyanov, was a Bulgarian revolutionary, anarchist and Kumanovo voivode of the Internal Macedonian-Adrianople Revolutionary Organisation (IMARO). He was born in 1877 in Chirpan, then part of the Ottoman Empire.

He studied in Plovdiv in 1891–1892 but did not complete his education because of financial difficulties. He worked as a printer in Plovdiv and Sofia, where he lived for a time with the poet Peyo Yavorov.

In 1895 he participated in the armed-detachment campaign organised by the Macedonian Committee. He left recollections of the uprising, published in "Voynishka Sbirka" (Soldiers' Collection) in 1901.

He embraced anarchist ideas and in 1900 entered the Gorna Dzhumaya region with a detachment. In January 1902 he was at IMARO's revolutionary post in Progled and participated in investigating the conditions for attacks in the Xanthi and Ahachelebi regions.

He is described as a young man with a restless, passionate nature, aggressive in disputes but honest and selfless.

In December 1902 he arrived in the Dedeagach region, where he and his associates were to assist Marin Cholakov and investigate possible attacks on the railway line.

Kosta Nunkov made unsuccessful attempts to carry out attacks during the Ilinden-Preobrazhenie Uprising. In July 1904 he became voivode in the Kumanovo region, where he fought Serbian armed propaganda in Macedonia. On 2 January 1905 he participated as a delegate at IMARO's Skopje Congress in Knezhevo.
