Nadezhda Konstantinovna Sigida (), née Malaxiano () (1862–1889), was a Russian revolutionary, heroine of the Kara katorga tragedy of 1889. Background Nadezhda Malaxiano was born into a Greek family in the city of Taganrog in 1862. She graduated from the Taganrog Mariinskaya Girls Gymnasium, and gave lessons in a church school. The family lived in a house on Gogolevski Street 8, next to Anton Chekhov's family house. Nadezhda Malaxiano became involved with a Narodnaya Volya group, being one of its activists in Taganrog's underground printshop in 1885–1886 on Glushko Street 60. She made a sham marriage with Akim Sigida (1868-1888) for conspiracy work at the printshop. The Don Process On 23 January 1886 following the disclosure of Narodnaya Volya's printers in Taganrog, she was arrested along with other organization members. The special hearing for her case was held in the Senate December 8–9, 1887 and was referred to as The Don Process (Донской процесс). At court, Nadezhda Sigida used the tactics of Narodnaya Volya, refusing to testify and only acknowledging her membership to the revolutionary organization. She was sentenced to death penalty. Sigida appealed for pardon following the request of Malaxiano family, and the death penalty was replaced by 8 years of katorga on Kara River in Transbaikalia. The Kara katorga tragedy Sigida was a participant with fellow women convicts in demanding the removal of the prison commandant, Lt.Col. Masiuyukov, who was allowing harsh treatment of the women convicts, as evidenced in the incident with Yelizaveta Kovalskaya in Aug. 1888. Two hunger strikes followed without any changes. Nadezhda Sigida then slapped Masiuyukov's face on 31 Aug. 1889. This resulted in her transfer into the criminal section of the prison at Ust Kara. A third hunger strike followed on 1 Sept. 1889, resulting in Marie Kaluzhnaya, Nadezhda Smirnitskya, and Marie Kavelefskaya being transferred to Ust Kara. The governor-general Andrei Korf sentenced Madam Sigida to 100 birch-rods, but the order was not immediately carried out following a report from the prison surgeon that she could not withstand the punishment. The governor-general reiterated the order and it was carried out on 6 Nov. 1889. In protest, Nadezhda Sigida and 23 other political prisoners took poison. Six died. They included Nadezhda Sigida on 8 Nov., Marie Kaluzhnaya, Nadezhda Smirnitskya, and Marie Kavelefskaya on 10 Nov., plus Ivan Kaluzhni, and Sergei Bobokhof on 16 Nov.
