Between the 15th and 19th century the town becomes popular under the name Kavarna, as a Christian settlement and port for grain export. From that time remain a Turkish bath, a medieval necropolis, a bridge, fountains, Christian churches and many inscriptions. During the Russo-Turkish War of 1877–1878 Kavarna's Christian inhabitants, Bulgarians and Gagauz alike, rebelled against the bashi-bazouks and Circassian hordes. After the liberation the town became part of the Principality of Bulgaria. From the beginning of 20th century Kavarna achieved a rapid progress as an economical and cultural centre. The town renamed Cavarna came under Romanian rule after the Second Balkan War in 1913 and again after the First World War in 1919. This however, was met with resistance by the local Bulgarian population and its Internal Dobrujan Revolutionary Organisation. In 1940 the town was ceded back to Bulgaria by the Treaty of Craiova.
