Voivode Sider Grancharov

Sider Kostadinov Grancharov, known as Sider the Voivode, was a Bulgarian participant in the national liberation movement. He belonged to the prominent merchant and National Revival Grancharov family.

Sider the Voivode was born in Gorna Oryahovitsa and traded in hides and spirits in partnership with his brothers Mosko and Vicho Grancharov. He joined the revolutionary cause under Vasil Levski's influence and became part of the local revolutionary committee's leadership, serving as treasurer of the district committee in Gorna Oryahovitsa.

In January 1876, Sider the Voivode became the district committee's chief representative in Wallachia for procuring arms. He facilitated the Danube crossings of the voivodes Father Hariton and Nikola Genchev Hainchanina and successfully smuggled large shipments of weapons before the April Uprising of 1876. Sider Grancharov bought about 70 rifles from Russia for Botev's detachment, but the weapons were stopped at the Russian-Romanian border, and he could not secure their release.

That same year, he volunteered in the Serbo-Turkish War under Filip Totyu's command. In July he led a detachment of about fifty men into western Bulgaria to provoke an uprising. However, the detachment was attacked by strong Turkish forces, and Sider Grancharov confronted them near the village of Churek on 31 July 1876, dying in battle near Murgash Peak.
