The Tran Uprising

The Tran Uprising, also known as the Shop Uprising or the Znepole–Kraishte Uprising, began on 30 December 1877, New Style, and was led by Captain Simo Sokolov.
In earlier years, after the decision to launch a nationwide uprising in Bulgaria, the Bulgarian Revolutionary Central Committee (BRCC) in Belgrade, including Simo Sokolov, Tseko Petkov, Ilyo Markov, Todor Tomich and Kalcho Paskov, established a Provisional Revolutionary Committee. Its purpose was to organise and lead the uprising in the western Bulgarian regions. Sokolov maintained contact with the BRCC and established connections in the Tran region, holding meetings and organising the uprising.
After the liberation of Pleven in December 1877, Serbia declared war on the Ottoman Empire, and Serbian troops captured several towns, including Pirot. Simo Sokolov and his detachment of around 1,000 fighters advanced towards Tran, liberating the regions of Breznik, Tran and Kyustendil. Despite their limited weaponry, their courage enabled them to liberate these areas.
Sokolov continued his activities after the armistice of 3 March 1878, extending the uprising into Macedonia, Egri Palanka, the Pčinja district and as far as Kratovo. He liberated towns and established unrestricted control over the territory. After western Bulgaria was freed from Serbian occupation, Sokolov remained an active patriot, supporting his fellow citizens in defending their membership of the Bulgarian state.
Sokolov settled in Sofia, became an officer in the Bulgarian army and was elected a member of parliament. He thus ended his active role in the liberation struggle while continuing to serve the Bulgarian people.

The Tran Uprising, associated with the First Bulgarian Legion, ended unsuccessfully. Despite Bulgarian voivodes' attempts to liberate Bulgaria, the Serbian authorities disbanded the legion in 1862 following unsuccessful fighting in the Gabrovo and Tryavna region.
