Cretan Revolt
All Greeks were united, however, in their determination to liberate the Greek-speaking provinces of the Ottoman Empire. Especially in Crete, the Cretan Revolt (1866–1869) raised nationalist fervour. When war broke out between Russian and the Ottomans in the Russo-Turkish War (1877–1878), Greek popular sentiment rallied to Russia's side, but Greece was too poor and too concerned about British intervention to enter the war officially. Nevertheless, in 1881, Thessaly and small parts of Epirus were ceded to Greece as part of the Treaty of Berlin.
