Traditionally, it is limited by the Apennines to the south-west, the Adriatic to the east, and the rivers Reno and Sillaro to the north and west. The region's major cities include Cesena, Faenza, Forlì, Imola, Ravenna, Rimini and City of San Marino (San Marino is a landlocked state inside the Romagna historical region). The region has been recently formally expanded with the transfer of seven comuni (Casteldelci, Maiolo, Novafeltria, Pennabilli, San Leo, Sant'Agata Feltria, Talamello) from the Marche region, which are a small number of comuni where Romagnolo dialect is spoken. Etymology. The name "Romagna" comes from the Latin name "Romània", which originally was the generic name for "land inhabited by Romans", and first appeared on Latin documents in the 5th century. It later took on the more detailed meaning of "territory subjected to Eastern Roman rule", whose citizens called themselves Romans ("Romani" in Latin; "Romàioi" in Greek). Thus the term "Romània" came to be used to refer to the territory administered by the Exarchate of Ravenna in contrast to other parts of Northern Italy under Lombard rule, named "Langobardia" or "Lombardy". "Romània" later became "Romandìola" in Vulgar Latin, meaning "little Romània", which became "Romagna" in modern times. History. Prehistory. A number of archaeological sites in the region, such as Monte Poggiolo, show that Romagna has been inhabited since the Paleolithic age.  - Squillace is an ancient seaside town and "comune", in the Province of Catanzaro, part of Calabria, southern Italy, facing the Gulf of Squillace.  - The Prince is a 16th-century political treatise, by the Italian diplomat and political theorist, Niccolò Machiavelli. From correspondence a version appears to have been distributed in 1513, using a Latin title, "De Principatibus" ("About Principalities"). However, the printed version was not published until 1532, five years after Machiavelli's death. This was done with the permission of the Medici pope Clement VII, but "long before then, in fact since the first appearance of "The Prince" in manuscript, controversy had swirled about his writings".  - The Black Rose is a 1950 20th Century Fox Technicolor film starring Tyrone Power and Orson Welles, loosely based on Thomas B. Costain's book. It was filmed partly on location in England and Morocco which substitutes for the Gobi Desert of China. The film was partly conceived as a follow-up to the movie "Prince of Foxes", and reunited the earlier film's two stars. Talbot Jennings' screenplay was based on a popular novel of the same name by Canadian author Thomas B. Costain, published in 1945, introducing an anachronistic Saxon rebellion against the Norman aristocracy as a vehicle for launching the protagonists on their journey to the Orient.   - Duke of Valentinois, formerly Count of Valentinois, is a title of nobility, originally in the French peerage. Though the duchy was once associated with administrative authority as well as possession of manors in Valence in France's "", those noble prerogatives were whittled away and by the 20th century it was a nominal dukedom consisting of a hereditary title descending in the male line.  - Prince of Foxes is a 1947 historical novel by Samuel Shellabarger, following the adventures of the fictional Andrea Orsini, a captain in the service of Cesare Borgia during his conquest of the Romagna.  - Samuel Shellabarger (18881954) was an American educator and author of both scholarly works and best-selling historical novels. He was born in Washington, D.C., on 18 May 1888. His parents both died while he was a baby. Samuel was therefore reared by his grandfather, Samuel Shellabarger, a noted lawyer who had served in Congress during the American Civil War and as Minister to Portugal. Young Samuel's travels with his grandfather later proved a goldmine of background material for his novels.    What entity does 'prince of foxes ' has the relation 'production company' with?
