It is one of three separate royal houses referred to as "Angevin", meaning "from Anjou" in France. Founded by Charles I of Naples, a son of Louis VIII of France, the Capetian king first ruled the Kingdom of Sicily during the 13th century. Later the War of the Sicilian Vespers forced him out of the island of Sicily, leaving him with just the southern half of the Italian Peninsula  the Kingdom of Naples.

Their name translates from Romanian as Mountains "of the sunset" i.e. "western". The highest peak is Cucurbta Mare at 1849 metres, also called Bihor Peak. The Apuseni Mountains have about 400 caves.  - Istria (Croatian, Slovene: "Istra"; Istriot: "Eîstria"; German: "Istrien"), formerly "Histria" (Latin), is the largest peninsula in the Adriatic Sea. The peninsula is located at the head of the Adriatic between the Gulf of Trieste and the Kvarner Gulf. It is shared by three countries: Croatia, Slovenia, and Italy.  - The Drava or Drave is a river in southern Central Europe. With a length of , it is the fourth longest tributary of the Danube. Its source is near the market town of Innichen (San Candido), in the Puster Valley of South Tyrol, Italy. The river flows eastwards through East Tirol and Carinthia in Austria into the Styria region of Slovenia.

The Adriatic is the northernmost arm of the Mediterranean Sea, extending from the Strait of Otranto (where it connects to the Ionian Sea) to the northwest and the Po Valley. The countries with coasts on the Adriatic are Albania, Bosnia and Herzegovina, Croatia, Greece, Italy, Montenegro and Slovenia. The Adriatic contains over 1,300 islands, mostly located along its eastern, Croatian, coast. It is divided into three basins, the northern being the shallowest and the southern being the deepest, with a maximum depth of . The Otranto Sill, an underwater ridge, is located at the border between the Adriatic and Ionian Seas. The prevailing currents flow counterclockwise from the Strait of Otranto, along the eastern coast and back to the strait along the western (Italian) coast. Tidal movements in the Adriatic are slight, although larger amplitudes are known to occur occasionally. The Adriatic's salinity is lower than the Mediterranean's because the Adriatic collects a third of the fresh water flowing into the Mediterranean, acting as a dilution basin. The surface water temperatures generally range from in summer to in winter, significantly moderating the Adriatic Basin's climate.  - The Sava is a river in Central Europe, a right side tributary of the Danube. It flows through Slovenia, Croatia, along the northern border of Bosnia and Herzegovina, through Serbia, discharging into the Danube in Belgrade. Its central part is a natural border of Bosnia-Herzegovina and Croatia.

Thereafter, he claimed the island, though his power was restricted to the peninsular possessions of the kingdom, with his capital at Naples (and for this he is usually titled King of Naples after 1282, as are his successors).  - Criana (Hungarian: "Körösvidék") is a geographical and historical region divided today between Romania and Hungary, named after the Cri (Körös) River and its three tributaries: the Criul Alb, Criul Negru, and Criul Repede.  - Slavonski Brod is a city in eastern Croatia, with a population of 59,000 in 2011. Located in the region of Slavonia, it is the centre of Brod-Posavina County and a river port on the Sava river.  - Stephen , Duke of Slavonia ( 26 December 1332 -- 9 August 1354 ) , was a Hungarian prince of the Capetian House of Anjou who served as governor of the provinces of Transylvania , Slavonia , Dalmatia and Croatia during the reign of his brother , King Louis I.  - Slavonia is, with Dalmatia, Croatia proper, and Istria, one of the four historical regions of Croatia. Taking up the east of the country, it roughly corresponds with five Croatian counties: Brod-Posavina, Osijek-Baranja, Požega-Slavonia, Virovitica-Podravina and Vukovar-Srijem, although the territory of the counties includes Baranya, and the definition of the western extent of Slavonia as a region varies. The counties cover or 22.2% of Croatia, inhabited by 806,19218.8% of Croatia's population. The largest city in the region is Osijek, followed by Slavonski Brod and Vinkovci. It is located in the Pannonian Basin, largely bordered by the Danube, Drava and Sava rivers.

Slavonia enjoys a moderate continental climate, with relatively low precipitation.  - The Kingdom of Sicily (, , ) was a state that existed in the south of the Apennine peninsula from its founding by Roger II in 1130 until 1816. It was a successor state of the County of Sicily, which had been founded in 1071 during the Norman conquest of the southern peninsula. Until 1282 the Kingdom (sometimes called the "regnum Apuliae et Siciliae", ""Kingdom of Apulia and Sicily"") covered not only the island of Sicily, but also the whole Mezzogiorno region of the southern Apennines and the Maltese archipelago. The island was divided into three regions: Val di Mazara, Val Demone and Val di Noto; 'val' being the Arabic word meaning 'district'.  - Louis VIII the Lion (5 September 1187  8 November 1226) was King of France from 1223 to 1226.

Historians in the 19th century came to apply the name "Capetian" to both the ruling house of France and to the wider-spread male-line descendants of Hugh Capet. It was not a contemporary practice (see House of France). They were sometimes called "the third race of kings", the Merovingians being the first, and the Carolingians being the second. The name is derived from the nickname of Hugh, the first Capetian King, who was known as "Hugh Capet". The direct succession of French kings, father to son, from 987 to 1316, of thirteen generations in almost 330 years, was unparallelled in recorded history.  - A natural border is a border between states or their subdivisions which is concomitant with natural formations such as rivers, mountain ranges, or deserts. The "doctrine of natural boundaries" developed in Western culture in the 17th century being based upon the "natural" ideas of Rousseau and developing concepts of nationalism. The similar concept in China developed earlier from natural zones of control.  - The War of the Sicilian Vespers or just War of the Vespers was a conflict that started with the insurrection of the Sicilian Vespers against Charles of Anjou in 1282, and ended in 1302 with the peace of Caltabellotta.

Bound on the east and south by its natural borders, the Carpathian mountain range, historical Transylvania extended westward to the Apuseni Mountains. The term sometimes encompasses not only Transylvania proper, but also the historical regions of Criana, Maramure, and the Romanian part of Banat.  - Croatia proper is one of the four historical regions of the Republic of Croatia, together with Dalmatia, Slavonia, and Istria. It is located between Slavonia in the east, the Adriatic Sea in the west, and Dalmatia to the south.
