Voivode Ango Kostadinov

Ango Kostadinov was a revolutionary and hajduk who served as a Supreme Macedonian-Adrianople Committee commander. His nicknames included Dyado Ancho, Dyado Avgo, Petrichki and Dalgiya.

Born in 1831 in Churicheni near Petrich in the Ottoman Empire, Dyado Ango became a hajduk and joined the Macedonian Committee. During the armed campaign of 1895, he led twenty-five men in the Pirin Mountains. He later joined other bands, including those of Boris Sarafov and Kocho Mustruka, bringing their combined strength to sixty-five. He took part in the brief capture of Melnik and subsequently became a Supreme Committee commander.

According to Yordan Venedikov, in late 1899 or early 1900, a band led by Dyado Ango and Doncho Zlatkov attacked a committee courier in Macedonia and stole about 200 napoleons intended for the committee's internal use. Sarafov demanded both commanders' execution, but Venedikov refused to 'shed blood'. Dyado Ango received twenty-five strokes of the cane, while Doncho escaped.

He also took part in the Gorna Dzhumaya Uprising of 1902 and the Ilinden–Preobrazhenie Uprising of 1903, serving on the staff of the Belasitsa Detachment. Chief of Staff Petar Darvingov mentioned him in his diary on 17 August, as the detachment climbed into the Pirin Mountains.
