Catalonia in the context of CODATA

Andorra, officially the Principality of Andorra, is a landlocked country on the Iberian Peninsula, in the eastern Pyrenees in Southwestern Europe, bordered by France to the north and Spain to the south. Believed to have been created by Charlemagne, Andorra was ruled by the count of Urgell until 988, when it was transferred to the Diocese of Urgell. The present principality was formed by a charter in 1278. It is currently headed by two co-princes: the Bishop of Urgell in Catalonia, Spain, and the president of France. Its capital and largest city is Andorra la Vella.

Andorra is the sixth-smallest state in Europe, with an area of 468 square kilometres (181 sq mi) and a population of approximately 87,486. The Andorran people are a Romance ethnic group closely related to Catalans. Andorra is the world's 16th-smallest country by land and 11th-smallest by population. Its capital, Andorra la Vella, is the highest capital city in Europe, at an elevation of 1,023 metres (3,356 feet) above sea level. The official language is Catalan, but Spanish, Portuguese, and French are also commonly spoken.

Llívia (Catalan pronunciation: [ˈʎiβiə]; Spanish: Llivia Spanish: [ˈʎiβja] ) is a town in the comarca of Cerdanya, province of Girona, Catalonia, Spain. It is a Spanish exclave surrounded by the French département of Pyrénées-Orientales. It is named after Livia, the wife of Augustus and matriarch of the Julio-Claudian dynasty. Because of a technicality in the Treaty of the Pyrenees, signed in 1659, that transferred only "villages" in the Pyrenees to France, Llívia, which was a "town", remains under Spanish control. The Segre river, a tributary of the Spanish Ebro, flows through Llívia. It has a population of 1,560 (register office, 2024) .

Llívia is separated from the rest of Spain by a corridor approximately 1.6 km (1.0 mile) wide, which includes the French communes of Ur and Bourg-Madame. This corridor is traversed by a road, owned by both France (where it is part of Route nationale 20 and RD68) and Spain (where it is part of N-154). Before the implementation of the Schengen Area in 1995, it was considered a "neutral road", a custom-free route with access for both French and Spanish people; since 1995, there have been no formal borders. The two countries share a hospital in Puigcerdà (which lies close to Llívia), as well as other local initiatives.

Phocaea or Phokaia (Ancient Greek: Φώκαια, Phókaia; modern-day Foça in Turkey) was an ancient Ionian Greek city on the western coast of Anatolia. Greek colonists from Phocaea founded the colony of Massalia (modern-day Marseille, in France) in 600 BC, Emporion (modern-day Empúries, in Catalonia, Spain) in 575 BC and Elea (modern-day Velia, in Campania, Italy) in 540 BC.

The Ligures (Latin sg. Ligus; also Ligustici or Ligustini) or in English Ligurians, were an ancient people after whom Liguria, a region of present-day north-western Italy, is named. Because of the strong Celtic influences on their language and culture, they were also known in antiquity as Celto-Ligures and hence in English as Celto-Ligurians.

In pre-Roman times, the Ligurians occupied the present-day Italian region of Liguria, Piedmont, northern Tuscany, western Lombardy, western Emilia-Romagna, and northern Sardinia, reaching also Elba and Sicily. They inhabited also the French region of Provence-Alpes-Côte d'Azur and Corsica; however, it is generally believed that around 2000 BC the Ligurians occupied a much larger area, extending as far as what is today Catalonia (in the north-eastern corner of the Iberian Peninsula).

The langues d'oïl  are a dialect continuum that includes standard French and its closest relatives historically spoken in the northern half of France, southern Belgium, and the Channel Islands. They belong to the larger category of Gallo-Romance languages, which also include the historical languages of east-central France and western Switzerland, southern France, portions of northern Italy, the Val d'Aran in Spain, and under certain acceptations those of Catalonia.

Linguists divide the Romance languages of France, and especially of Medieval France, into two main geographical subgroups: the langues d'oïl to the north, and the langues d'oc in the southern half of France. Both groups are named after the word for yes in their recent ancestral languages. The most common modern langue d'oïl is standard French, in which the ancestral oïl has become oui.

The Diocese of Urgell (Catalan pronunciation: [uɾˈ(d)ʒeʎ]; Latin: Diœcesis Urgellensis) is a Latin Church diocese of the Catholic Church in Catalonia (Spain) and the Principality of Andorra in the historical County of Urgell, with origins in the 5th century AD or possibly earlier. It is based in the region of the historical Catalan County of Urgell, though it has different borders. The seat and cathedral of the bishop are situated in la Seu d'Urgell town. The state of Andorra is a part of this diocese.

Among its most notable events are Bishop Felix's adoptionist revolt, the coup of Bishop Esclua, and the overthrowing of the bishop by members of aristocratic families (namely Salla i Ermengol del Conflent, Eribau i Folcs dels Cardona, Guillem Guifré de Cerdanya and Ot de Pallars) between the years 981 and 1122.

Catalans (Catalan, French and Occitan: catalans; Spanish: catalanes; Italian: catalani; Sardinian: cadelanos or catalanos) are a Romance-speaking ethnic group native to Catalonia, who speak Catalan. The current official category of "Catalans" is that of the citizens of Catalonia, a nationality and autonomous community in Spain and the inhabitants of the Roussillon historical region in Southern France, today the Pyrénées Orientales department, also called Northern Catalonia and Pays Catalan in French.

Some authors also extend the word "Catalans" to include all people from areas in which Catalan is spoken, namely those from Andorra, Valencia, the Balearic Islands, eastern Aragon, and the city of Alghero in Sardinia.

Catalan (català) is a Western Romance language. It is the official language of Andorra and the official language of three autonomous communities in eastern Spain: Catalonia, the Balearic Islands and the Valencian Community, where it is called Valencian (valencià). It has semi-official status in the Italian municipality of Alghero, and it is spoken in the Pyrénées-Orientales department of France and in two further areas in eastern Spain: the eastern strip of Aragon and the Carche area in the Region of Murcia. The Catalan-speaking territories are often called the Països Catalans or "Catalan Countries".

The language evolved from Vulgar Latin in the Middle Ages around the eastern Pyrenees. It became the language of the Principality of Catalonia and the kingdoms of Valencia and Mallorca, being present throughout the Mediterranean as the main language of the Crown of Aragon. It was replaced by Spanish as a language of government and literature in the 1700s, but nineteenth century Spain saw a Catalan literary revival, culminating in the early 1900s. With the end of Franco dictatorship (1975) and its repressive measures against the language, Catalan entered a relatively successful process of re-normalization between the 1980s and the 2000s. However, during the 2010s, it experienced signs of decline in social use, diglossia and the re-growth of discrimination cases.

The County of Flanders was one of the most powerful political entities in the medieval Low Countries, located on the North Sea coast of modern-day Belgium and north-eastern France. Unlike the neighbouring states of Brabant and Hainaut, it was within the territory of the Kingdom of France. The counts of Flanders held the most northerly part of the kingdom, and were among the original twelve peers of France. For centuries, the economic activity of the Flemish cities, such as Ghent, Bruges and Ypres, made Flanders one of the most affluent regions in Europe, and also gave them strong international connections to trading partners.

Up to 1477, the core area under French suzerainty was west of the Scheldt and historians call this "Royal Flanders" (Dutch: Kroon-Vlaanderen, French: Flandre royale). Aside from this, the counts, from the 11th century onward, held land east of the river as a fief of the Holy Roman Empire, and this is referred to as "Imperial Flanders" (Rijks-Vlaanderen or Flandre impériale). From 1384, the county was politically united to the Duchy of Burgundy, and it formed the starting point for more acquisitions in the area, and the eventual creation of the Burgundian Netherlands. The expansion of Flemish ("Burgundian") power deep into the Holy Roman Empire further complicated the relationship between Flanders and France, but reinforced the connections with Brabant, Hainaut, Holland and other parts of the Low Countries. The link to the empire was strengthened even more when the Burgundian Netherlands came into the hands of the imperial Habsburg dynasty in 1477. Most of Flanders became part of the empire after the Peace of Madrid in 1526 and the Peace of the Ladies in 1529, although it came to be ruled under the Habsburg crown of Spain. The territories of the old county are now the only part of the late medieval French kingdom outside of modern-day France, Catalonia having been renounced in 1258.

Urgell (Catalan pronunciation: [urˈ(d)ʒeʎ]), also known as Baix Urgell (baix meaning "lower", by contrast with Alt Urgell "Upper Urgell"), is a comarca (county) in Ponent, Catalonia (Spain), forming only a borderland portion of the region historically known as Urgell, one of the Catalan counties.

The capital is the city of Tàrrega.

Barcelona (/ˌbɑːrsəˈloʊnə/ BAR-sə-LOH-nə; Catalan: [bəɾsəˈlonə] ; Spanish: [baɾθeˈlona] ) is a city on the northeastern coast of Spain. It is the capital and largest city of the autonomous community of Catalonia, as well as the second-most populous municipality of Spain. With a population of 1.7 million within city limits, its urban area extends to numerous neighbouring municipalities within the province of Barcelona and is home to around 5.7 million people, making it the fifth most populous urban area of the European Union after Paris, the Ruhr area, Madrid and Milan. It is one of the largest metropolises on the Mediterranean Sea, located on the coast between the mouths of the rivers Llobregat and Besòs, bounded to the west by the Serra de Collserola mountain range.

According to tradition, Barcelona was founded by either the Phoenicians or the Carthaginians, who had trading posts along the Catalonian coast. In the Middle Ages, Barcelona became the capital of the County of Barcelona. After joining with the Kingdom of Aragon to form the composite monarchy of the Crown of Aragon, Barcelona, which continued to be the capital of the Principality of Catalonia, became the most important city in the Crown of Aragon and its main economic and administrative centre, only to be overtaken by Valencia, wrested from Moorish control by the Catalans, shortly before the dynastic union between the Crown of Castile and the Crown of Aragon in 1516. Barcelona became the centre of Catalan separatism, briefly becoming part of France during the 17th century Reapers' War and again in 1812 until 1814 under Napoleon. Experiencing industrialization and several workers movements during the 19th and early 20th century, it became the capital of autonomous Catalonia in 1931 and it was the epicenter of the revolution experienced by Catalonia during the Spanish Revolution of 1936, until its capture by the fascists in 1939. After the Spanish transition to democracy in the 1970s, Barcelona once again became the capital of an autonomous Catalonia.

The Roman Republic conquered and occupied territories in the Iberian Peninsula that were previously under the control of native Celtic, Iberian, Celtiberian and Aquitanian tribes and the Carthaginian Empire. The Carthaginian territories in the south and east of the peninsula were conquered in 206 BC during the Second Punic War. Control was gradually extended over most of the peninsula without annexations. It was completed after the end of the Roman Republic (27 BC), by Augustus, the first Roman emperor, who annexed the whole of the peninsula to the Roman Empire in 19 BC.

This conquest started with the Roman acquisition of the former Carthaginian territories in southern Hispania and along the east coast as a result of defeating the Carthaginians (206 BC) during the Second Punic War (218–201 BC), after which the Carthaginian forces left the peninsula. This resulted in an ongoing Roman territorial presence in southern and eastern Hispania. In 197 BC, the Romans established two Roman provinces. These were Hispania Citerior (Nearer Spain) along most of the east coast (an area corresponding to the modern Valencia, Catalonia and part of Aragon) and Hispania Ulterior (Further Spain) in the south, corresponding to modern Andalusia.

The Esteve Pharmacy (Catalan: Farmàcia Esteve, IPA: [fəɾˈmasiə əsˈteβə]) is a medieval pharmacy and museum located in the town of Llívia, in the comarca of Cerdanya, Catalonia, Spain. Llívia is a Spanish exclave within the French region of Pyrénées-Orientales. The Esteve Pharmacy, founded at the beginning of the 15th century, is one of the oldest pharmacies in Europe and keeps a collection of albarellos from the 16th and 17th centuries, glass from the 19th century, Renaissance boxes with portraits of saints and personages, a library, laboratory instruments, antique drugs and preparations, old prescription books, and a Baroque "cordialer" cupboard made by Josep Sunyer during the period when the Esteve family managed the pharmacy for up to seven generations. It is one of the most important collections of its kind in Europe.

In 1942, Lleó Antoni Esteve closed the pharmacy and moved to Puigcerdà. In 1958 the pharmacy was transferred to the town of Llívia, and the Province of Girona Diputació purchased it in 1965.

The comarques of Catalonia (singular comarca, Eastern Catalan: [kuˈmarkə], Western Catalan: [koˈmaɾka]), often referred to in English as counties, are an administrative division of Catalonia. Each comarca comprises a number of municipalities, roughly equivalent to a county in the United States. Currently, Catalonia is divided into 42 comarques and Aran, considered a "unique territorial entity" and not a comarca.

Each comarca has a representative county council (Catalan: consell comarcal), except for Barcelonès, which abolished it in 2019, and Aran, which instead has the Conselh Generau d'Aran.

Cerdanya (Catalan pronunciation: [səɾˈðaɲə]; Spanish: Baja Cerdaña, pronounced [ˈbaxa θeɾˈðaɲa]; French: Basse-Cerdagne, pronounced [bɑs sɛʁdaɲ, bas-]) is a comarca in northern Catalonia, in the Pyrenees, on the border of Catalonia with France and Andorra. Within Catalonia, Cerdanya is divided between Catalan provinces of Girona and Lleida. Cerdanya's neighbouring comarques are Alt Urgell, Berguedà, and Ripollès.

Cerdanya is in the "vegueria" of Alt Pirineu, according to "Vegueries of Catalonia law".

The Province of Girona (Catalan: província de Girona [pɾuˈvinsiə ðə ʒiˈɾonə]; Spanish: provincia de Gerona [pɾoˈβinθja ðe xeˈɾona]) is a province in the northeastern part of the autonomous community of Catalonia, Spain. It is bordered on the northwest by the province of Lleida, on the southwest by the province of Barcelona, on the north by France (Pyrénées-Orientales), and on the east by the Mediterranean Sea.

The population of the province in 2016 was 739,607. Its capital and largest city is Girona, with an urban area (including the neighbouring municipalities of Salt, Sarrià de Ter and Vilablareix) representing, with a total population of 144,709, 19.2% of the population. The Girona area acts as an industrial, commercial and service hub for a significant part of the province.

Pyrénées-Orientales (French: [piʁene ɔʁjɑ̃tal] ; Catalan: Pirineus Orientals [piɾiˈnɛwz uɾiənˈtals]; Occitan: Pirenèus Orientals [piɾeˈnɛwz uɾjenˈtals]; lit. 'Eastern Pyrenees'), also known as Northern Catalonia, is a department of the region of Occitania, Southern France, adjacent to the northern Spanish frontier and the Mediterranean Sea. It borders the departments of Ariège to the northwest and Aude to the north, the Mediterranean Sea to the east and the Spanish province of Girona in Catalonia to the south and the country of Andorra to the west. It also surrounds the tiny Spanish exclave of Llívia, and thus has two distinct borders with Spain. In 2019, it had a population of 479,979. Some parts of the Pyrénées-Orientales (like the Cerdagne) are part of the Iberian Peninsula. It is named after the Pyrenees mountain range.

The Ebro (Spanish and Basque [ˈeβɾo] ; Catalan: Ebre, Western: [ˈeβɾe], Eastern: [ˈeβɾə]) is a river of the north and northeast of the Iberian Peninsula, in Spain. It rises in Cantabria and flows 930 kilometres (580 mi), almost entirely in an east-southeast direction. It flows into the Mediterranean Sea, forming a delta in the Terres de l'Ebre region, in southern Catalonia. In the Iberian peninsula, it ranks second in length after the Tagus and second in discharge volume, and drainage basin, after the Douro. It is the longest river entirely within Spain; the other two mentioned flow into Portugal.

The Ebro flows through many cities (Spanish: ciudades): Reinosa in Cantabria; Frías and Miranda de Ebro in Castile and León; Haro, Logroño, Calahorra, and Alfaro in La Rioja; Tudela in Navarre; Alagón, Utebo, and Zaragoza in Aragon; and Flix, Móra d'Ebre, Benifallet, Tivenys, Xerta, Aldover, Tortosa, and Amposta in the province of Tarragona (Catalonia).
