Hispania (Hispānia hɪsˈpaːnia, isˈpanja; nearly identically pronounced in Spanish, Portuguese, Catalan, and Italian) was the Roman name for the Iberian Peninsula and its provinces. Under the Roman Republic, Hispania was divided into two provinces: Hispania Citerior and Hispania Ulterior. During the Principate, Hispania Ulterior was divided into two new provinces, Baetica and Lusitania, while Hispania Citerior was renamed Hispania Tarraconensis. Subsequently, the western part of Tarraconensis was split off, initially as Hispania Nova, which was later renamed "Callaecia" (or Gallaecia, whence modern Galicia). From Diocletian's Tetrarchy (AD 293) onwards, the south of the remainder of Tarraconensis was again split off as Carthaginensis, and all of the mainland Hispanic provinces, along with the Balearic Islands and the North African province of Mauretania Tingitana, were later grouped into a civil diocese headed by a vicarius. The name Hispania was also used in the period of Visigothic rule.
The modern place names Spain and Hispaniola are both derived from Hispania.
The origin of the word Hispania is very disputed. The evidence for the various speculations is based merely upon what are at best mere resemblances, likely to be accidental, and suspect supporting evidence. The most commonly held theory holds it to be of Punic origin, from the Phoenician language of colonizing Carthage. Specifically, it may derive from a Punic cognate ī shāpān (𐤀𐤉 𐤔𐤐𐤍) of Hebrew ī shāfān (אִי שָׁפָן) meaning 'island of the hyrax', referring to the European rabbit (Phoenician-Punic and Hebrew are both Canaanite languages and therefore closely related to each other). Some Roman coins of the Emperor Hadrian, born in Hispania, depict Hispania and a rabbit. Others derive the word from Phoenician span, meaning 'hidden', and make it indicate "a hidden", that is, "a remote", or "far-distant land".
Other far-fetched theories have been proposed. Isidore of Sevilla considered Hispania of Iberian origin and derived it from the pre-Roman name for Seville, Hispalis.
