The Kavarna massacre (Bulgarian: Каварненското клане), also known as the Kavarna rebellion (Bulgarian: Каварненското въстание), refers to the near one-month (7 July [O.S. 25 June] 1877–8 August [O.S. 27 July] 1877) defence of the Black Sea town of Kavarna by its citizens and some 10,000 refugees from nearby villages against a band of 3,000 Circassian paramilitaries.[1][2][3]
Even though Kavarna's defence was ultimately unsuccessful, with some 1,000 civilian casualties and half the town burned to the ground, the uprising is famous for both its fierce, implacable resistance and the sheer number of different ethnicities that took part in it: Bulgarians, Gagauzes, Greeks, Armenians and even the local Muslim Turkish population.
