Adria#

Adriatic Sea: Once Austria had established itself on the Adriatic by acquiring Trieste in 1382, it began to expand its position in Istria (1466 Rijeka = Fiume, 1719 a free port); Austria received the Dalmatian coast in the Treaty of Campo Formio in 1797, thus coming into conflict with Italy over predominance in the Adriatic after 1860. In the Treaty of London (1915) Italy received broad assurances from Western powers and as a consequence entered World War I on their side. However, Italy's desires were only partly fulfilled, and thus rivalry with Yugoslavia arose during the inter-war period; Yugoslavia received a considerable part of the formerly Austrian territories on the Adriatic (with the exception of Trieste) in 1946. Today, most of the coastal area belongs to Croatia; Slovenia only has the port of Koper.
