areas with natural grass, fertile soils, and warm summers provide an opportunity for tillage. Elsewhere, land cultivation is mostly unsuccessful because of the mountains, hot summers, and poor soils, although olives and grapes flourish. Energy resources are scarce. Electricity is mainly produced by hydropower stations. There is a considerable amount of bauxite. The largest Dalmatian mountains are Dinara, Mosor, Svilaja, Biokovo, Moseć, Veliki Kozjak, and Mali Kozjak. The regional geographical unit of historical Dalmatia–the coastal region between Istria and the Bay of Kotor–includes the Orjen mountains with the highest peak in Montenegro, 1894 m. In present-day Dalmatia, the highest peak is Dinara (1913 m), which is not a coastal mountain, while the highest coastal Dinaric mountains are on Biokovo (Sv. Jure, 1762 m) and Velebit (Vaganski vrh, 1757 m), although the Vaganski vrh itself is located in Lika-Senj County. The largest Dalmatian islands are Brač, Korčula, Dugi Otok, Mljet, Vis, Hvar, Pag and Pašman. The major rivers are Zrmanja, Krka, Cetina, and Neretva. The Adriatic Sea's high water quality, along with the immense number of coves, islands, and channels, makes Dalmatia an attractive place for nautical races, nautical tourism, and tourism in general. Dalmatia also includes several national parks that are tourist attractions: Paklenica karst river, Kornati archipelago, Krka river rapids, and Mljet island. Administrative division The area of Dalmatia roughly corresponds to Croatia's four southernmost counties, listed here north to south: History Antiquity Dalmatia's name is derived from the name of an Illyrian tribe called the Dalmatae who lived in the area of the eastern Adriatic coast in the 1st millennium BC. It was part of the Illyrian Kingdom between the 4th century BC and the Illyrian Wars (220, 168 BC) when the Roman Republic established its protectorate south of the river Neretva. The name "Dalmatia" was in use probably from the second half of the 2nd century BC and certainly from the first half of the 1st century BC, defining a coastal area of the eastern Adriatic between the Krka and Neretva rivers. It was slowly incorporated into Roman possessions until the Roman province of Illyricum was formally established around 32–27 BC. In 9 AD the Dalmatians raised the last in a series of revolts together with the Pannonians, but it was finally crushed and, in 10 AD, Illyricum was split into two provinces, Pannonia and Dalmatia, which spread into larger area inland to cover all of the
