Sassari is an Italian city and the second-largest of Sardinia in terms of population with 127,525 inhabitants, and a Functional Urban Area of about 260,000 inhabitants. One of the oldest cities on the island, it contains a considerable collection of art.
Archaeological evidence of prehistoric human settlement on the island of Sardinia is present in the form of nuraghes and other prehistoric monuments, which dot the land. The recorded history of Sardinia begins with its contacts with the various people who sought to dominate western Mediterranean trade in classical antiquity: Phoenicians, Punics and Romans. Initially under the political and economic alliance with the Phoenician cities, it was partly conquered by Carthage in the late 6th century BC and then entirely by Rome after the First Punic War. The island was included for centuries in the Roman province of Sardinia and Corsica, which would be incorporated into the diocese of Italia suburbicaria in 3rd and 7th centuries.
Eleanor of Arborea or Eleanor De Serra Bas was one of the most powerful and important, and one of the last, judges of the Judicate of Arborea in Sardinia, and Sardinia's most famous heroine. She is also known for updating of the Carta de Logu, promulgated by her father Marianus IV and revisited by her brother Hugh III.
The Judicates, in English also referred to as Sardinian Kingdoms, Sardinian Judgedoms or Judicatures, were independent states that took power in Sardinia in the Middle Ages, between the eleventh and fifteenth centuries. They were sovereign states with summa potestas, each with a ruler called judge, with the powers of a king.
Iglesias is a comune and city in the province of South Sardinia, Italy. It was co-capital of the province of Carbonia-Iglesias with Carbonia, and the province's second-largest community.
The Judicate of Arborea or the Kingdom of Arborea was one of the four independent judicates into which the island of Sardinia was divided in the Middle Ages. It occupied the central-west portion of the island, wedged between Logudoro to the north and east, Cagliari to the south and east, and the Mediterranean Sea to the west. To the northeast of Logudoro was Gallura, with which Arborea had far less interaction. Arborea outlasted her neighbours, surviving well into the 15th century. At its greatest territorial extent it occupied the entire island except the cities of Alghero and Cagliari. The earliest known judicial seat was Tharros, though Oristano served as capital for most of its existence.
Barison II or Barisone II was the "Judge" of Arborea, one of the four Judicates of Sardinia, from 1146 to 1186. He was the son of Comita II and Elena de Orrubu. His reign was groundbreaking in Sardinian history. It saw the birth of Catalan influence, the escalation of the Genoese-Pisan conflict, and the first royal investiture over the entire island when Barisone was briefly recognised as King of Sardinia by the Holy Roman Emperor from 1164 to 1165.
The Judicate of Cagliari was one of the four kingdoms or judicates into which Sardinia was divided during the Middle Ages.
The Judicate of Gallura was one of four Sardinian judicates in the Middle Ages. These were independent states whose rulers bore the title iudex, judge. Gallura, a name which comes from gallus, meaning rooster (cock), was subdivided into ten curatoriae governed by curatores under the judge. In the 13th century, the arms of Gallura contained a rooster.
Marianus IV, called the Great, was the Judge (king) of Arborea, kingdom in the island of Sardinia, from 1347 to his death. He was, as his nickname indicates, the greatest sovereign of Arborea. He was a legislator and a warrior whose reign saw the commencement of massive codification of the laws of his realm and incessant warfare with the Crown of Aragon. He was also a religious man, who had connections to Catherine of Siena. He was, in short, an "wise legislator, able politician, and valiant warrior."
Torchitorio V, born John and known as Chiano or Chianni, was the Giudice (Judge) of Cagliari from 1250 to his death. His reign was brief but transformative in the history of Sardinia.
Marianus II was the Judge of Arborea from 1241 to his death. With skilled military action, he came to control more than half of the island of Sardinia. By his control of the vast central plains and the rich deposits of precious metals, he increased the riches of his Judicate and staved off the general economic decline affecting the rest of Europe at the time.
Brancaleone Doria was the husband of Eleanor of Arborea, regent of the Giudicato of Arborea on the island of Sardinia in the late 14th century. He was a scion of the influential Doria family of the Republic of Genoa, the son of the elder Brancaleone and a woman named Giacomina. On 16 March 1357, he became a vassal of Peter IV of Aragon, the nominal King of Sardinia, to legitimate the possessions of his father on the island.
The Kingdom of Sardinia, also referred to as the Kingdom ofSardinia-Piedmont, Sardegna and Corsica or Piedmont–Sardinia as a composite state during the Savoyard period, was a country in Southern Europe from the late 13th until the mid-19th century; officially 1297 to 1768 for the Corsican part of this kingdom.
The Battle of Lucocisterna was fought on the 29 February 1324, during the Aragonese conquest of Sardinia, between the army of the Crown of Aragon, in command of the Infante Alfonso IV of Aragon, son of King James II of Aragon, and the army of the Republic of Pisa led by Manfredi della Gherardesca, Count of Donoratico.
The siege of Villa di Chiesa was carried out by the army of the Crown of Aragon and of the giudicato of Arborea, between the summer of 1323 and the winter of 1324. It represented the first act of the Aragonese conquest of Pisan Sardinia, for the creation of the Kingdom of Sardinia.
The Sardinian–Aragonese war was a late medieval conflict lasting from 1353 to 1420. The fight was over supremacy of the land and took place between the Judicate of Arborea -- allied with the Sardinian branch of the Doria family and Genoa -- and the Kingdom of Sardinia, the latter of which had been part of the Crown of Aragon since 1324.
The Free Municipality of Sassari or Republic of Sassari was a state in the region of Sassari in Sardinia during the 13th and 14th centuries, confederated first with the Republic of Pisa as a semi-autonomous subject and later with the Republic of Genoa as a nominally independent ally. It was the first and only independent city-state of Sardinia during the early renaissance.
The Kingdom of Sardinia was a feudal state in Southern Europe created in the early 14th century and a possession of the Crown of Aragon first and then of the Spanish Empire until 1708, then of the Habsburgs until 1717, and then of the Spanish Empire again until 1720.
The Catalan–Genoese War, also known as Aragonese–Genoese War was an armed conflict between the Crown of Aragon and the Republic of Genoa that lasted from 1330 to 1336
