Ragusa was once the only city in Dalmatia with Roman influence not to be controlled by the Republic of Venice. After the Middle Ages more and more Croats and Serbs from inland areas of Bosnia-Herzegovina moved to the area. They had started the neighbouring town of Dubrovnik, which eventually joined Ragusa. The original population (the Dalmatian Italians) was reduced to the few people of the ruling class: in the 19th century nearly all the people living in Ragusa were Slavs (Croats and Serbs). Ragusa officially changed its name to "Dubrovnik" (a Croatian name) after 1918, when the city became part of the newly created country of Yugoslavia.
