Georgi Nikolov Delchev (Bulgarian: Георги Николов Делчев; Macedonian: Ѓорѓи Николов Делчев; 4 February 1872 – 4 May 1903), known as Gotse Delchev or Goce Delčev (Гоце Делчев), was a prominent Macedonian Bulgarian revolutionary (komitadji) and one of the most important leaders of what is commonly known as the Internal Macedonian Revolutionary Organization (IMRO). He was active in the Ottoman-ruled Macedonia and Adrianople regions, as well as in Bulgaria, at the turn of the 20th century. Delchev was IMRO's foreign representative in Sofia, the capital of the Principality of Bulgaria. As such, he was also a member of the Supreme Macedonian-Adrianople Committee (SMAC) for a period, participating in the work of its governing body. He was killed in a skirmish with an Ottoman unit on the eve of the Ilinden-Preobrazhenie Uprising.
Born into a Bulgarian Millet affiliated family in Kukush (today Kilkis in Greece), then in the Salonika vilayet of the Ottoman Empire, in his youth he was inspired by the ideals of earlier Bulgarian revolutionaries such as Vasil Levski and Hristo Botev, who envisioned the creation of a Bulgarian republic of ethnic and religious equality, as part of an imagined Balkan Federation. Delchev completed his secondary education in the Bulgarian Men's High School of Thessaloniki and entered the Military School of His Princely Highness in Sofia, but at the final stage of his study, he was dismissed for holding socialist literature. Then he returned to Ottoman Macedonia and worked as a Bulgarian Exarchate schoolteacher, and immediately became an activist of the newly-found revolutionary movement in 1894.
