(Redirected from Giudicato di Arborea)
The ''Giudicati'' of Sardinia.
The '''Giudicato'' of Arborea' was one of the four independent, hereditary "judicatures" (''
giudicati'') into which the island of
Sardinia was divided in the
High 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 north west and beyong Logudoro was located
Gallura, with which Arborea had far less interaction. Arborea outlasted her neighbours, surviving well into the
fifteenth century. The earliest known judicial seat was
Tharros (Tarra).
Origins

The Eradicated Tree, symbol of Arborea.
In the early ninth century, when the
Arabs and
Berbers of
North Africa became aggressive in expansion and piracy, the
Byzantine Empire was unable to effectively defend Sardinia and so certain provincial judges assumed independent authority over and provision for local defence. The island became divided into four ''iudicati'', local autonomous provinces ruled by ''iudices''. By the tenth century, these districts had become hereditary or rotated amongst a few most powerful clans.
The first important judge (''giudice'') of Arborea was
Marianus I (ruled
1060 –
1070) of the
Thori family. In 1070, his successor,
Orzocorre I moved the capital from the ancient port of Tharros, which was exposed to Arab attacks, to
Oristano. At about that time, Sardinia begins to emerge from obscurity and come into the historian's view. Under the ambitious
Pope Gregory VII, then leading a
papal reform, Sardinia was integrated into the wider Christendom. By the infusion of
Western monasticism and
Pisan ecclesiastic rule, she became involved in the conflicts and commerce of Europe.
Lacon dynasty
Under
Constantine I of the
Lacon dynasty, Arborea paid tribute to the papacy and sponsored
Camaldolese monks, in opposition to the monks of
Marseille favoured by rival Cagliari. Constantine did homage to Pisa for his ''giudicato'' and was successor was his brother
Comita II. When
Pope Innocent II divided Sardinia between the sees of Pisa and
Genoa in
1133, Arborea fell to the former, but Comita, for reasons of furthering Arborean independence, allied with Genoa during the subsequent civil wars of that decade. In
1145, Comita was excommunicated by
Baldwin, Archbishop of Pisa, and the ''giudicato'' of Arborea was nominally transferred to Logudoro.
Comita's son and successor,
Barison II, put Arborea back on good terms with Pisa. He married into the
Catalan nobility, creating ties to Spain which culminated in Sardinia falling to the
Crown of Aragon some centuries later. In
1164, Barison paid the
Holy Roman Emperor Frederick Barbarossa to have him crowned
King of Sardinia, but the emperor revoked that title the next year, though Barison continued to employ it. He finally left Pisa for Genoa, but his legacy was civil war. His son
Peter I and grandson
Hugh I finally divided the ''giudicato'' by the
Treaty of Oristano (
1192), but in the end Hugh's line, the
House of Cervera (or
Bas), succeeded in establishing themselves.
Catalan dynasty
While
Peter II, son of Hugh, has been accused by historians of impoverishing his realm of glory, his son
Marianus II expanded it substantially, even ruling over a majority of the island. During the final decades of the thirteenth century, three other ''giudicati'' fell into the hands of either Pisa or Genoa or one of their great families, but Arborea remained independent.
Hugh II (ruled
1321 –
1336), great-grandson of Marianus II, headed up a faction which favoured
James II of Aragon, who had been promised the island by pope, as overlord. He supported the
''Infante'' Alfonso in his campaign (
1323 –
1324) to conquer the island from Pisa and Genoa. In
1336, Hugh II was succeeded by his son
Peter III (died
1345). His brother
Marianus IV (ruled
1353 –
1375) was the only Sardinian ruler to be known as "the Great." He was educated at the Aragonese court, but later turned against his cultural allies and led a victorious revolt against the invaders, both Ligurian and Spanish. A period of splendour commenced. Oral traditions were codified and new legislation enacted. Army and tactics were reformed. With the exception of Cagliari,
Alghero, and
Sassari (then under
Brancaleone Doria), Marianus conquered the whole of the island, making Arborea the strongest any ''giudicato'' had ever been.
Marianus was succeeded by his son
Hugh III, who furthered his father's legislation and died without descendants in
1383. A republic was proclaimed, but the crown was claimed by
Eleanor, elder sister of Hugh III, who was married to Brancaleone Doria. She succeeded in power in
1387. Eleanor was technically regent on behalf of her sons
Frederick and, subsequently,
Marianus V. Eleanor died in
1404 and Marianus in
1407: after the latter's death the succession descended to
William III of Narbonne, grandson of Beatrice, Eleanor's sister. He defended the island against the Catalan troops of the
Martin of Aragon, but
Martin I of Sicily vanquished them in the
Battle of Sanluri on
30 June 1409. Martin's sudden death made possible a recovery and occupation of Sassari and part of Logoduro, as well as reclamation of the title of Judge of Arborea by William. However, all the Arborean castles fell after a renewed Catalan offensive and Oristano fell in March
1410 without resistance.
Leonard Cubell laid claim to the title of Judge of Arborea, but was compelled in Oristano by
Pedro de Torrelles to renounce the title, after which he was given the
Marquisate of Oristano and
County of Gucea. In
1420,
Alfonso V of Aragon purchased for 100,000
gold florins the rights of the viscounts of Narbonne. Later, the Aragonese governor,
Leonardo de Alagon, rebelled and was also able to beat the king's troops at
Uras in
1470. However, his defeat at the
Battle of Macomer (
1478) put a definitive end to the independence of Arborea and Sardinia.
Curatoriae

The ''curatoriae'' of Arborea.
Arborea was divided into thirteen (at times, fourteen) ''curatoriae'' or ''partes'' (sing. ''curatoria'' and ''partis''). These were the main administrative regions, governed by ''curatores'' (curators) under the judge. The subdivisions of the ''curatoriae'' were the ''villae'', the inhabited centres (villages) that, altogether, probably comprised 100,000 inhabitants. The ''curatoriae'' were an inheritance of Byzantine government and are still recognised today as "historic regions."
The fourteen ''curatoriae'' of Arborea were
Barbagia di Belvì,
Barbagia d’Ollolai,
Barigadu,
Bonorzuli,
Campidano di Cabras,
Campidano di Milis,
Campidano di Simaxis,
Guilcier,
Mandrolisai,
Marmilla,
Montis,
Usellus,
Valenza, and
Brabaxiana.
Historiography
The history of Arborea is based on slender documentation, most of it assembled in the archives of Pisa and Genoa and viewing Arborea and the other ''giudicati'' through a colonial lens. John Day concentrates on attempting to reconstruct the socio-economic history; the internal social structure of Arborea still remains silent.
The evaluation of political figures has traditionally been made on the basis of military accomplishment, whereas Nowé points out that the ecclesiastical policy of the rulers of Sardinia was just as important in determining the stability, peacefulness, and long-term success of the ''giudicati'' in the face of colonialism.
