Rijeka, Croatia, a city in the northwestern part of the country, on the Kvarner Gulf of the Adriatic Sea. Behind the city rises a coastal range of the Dinaric Alps, peaking at about 5,000 feet (1,500 m). Rijeka is a major seaport and an industrial city with shipbuilding, petroleum refining, and other manufacturing. The University of Rijeka, an ancient Roman gate, a 13th-century cathedral, and several museums are here. Nearby are several seaside resorts, most notably Opatija.

Rijeka has been a part of the Roman, Byzantine, French, and Austrian empires. The city was Hungary's chief seaport from 1779 until World War I. After World War I possession of Rijeka was disputed by Italy and Yugoslavia. In 1919 Gabriele D' An-nunzio with a small company of Italian troops seized the city and proclaimed it an independent state. D' Annunzio was ousted after 15 months, and in 1924 Rijeka was taken over by Italy and named Fiume. Susak, an eastern suburb now included in Rijeka, became part of Yugoslavia. Following World War II, Yugoslavia gained possession of the entire city. It was under Yugoslav control until Croatia became independent in 1992.
