In 1355
Peter IV called a parliament of the Sardinian nobility in order to address the resistance to his rule of Judge
Marianus IV of Arborea, but the greater nobles refused to attend. This was nevertheless the first Sardinian parliament. One of its acts was to exclude all those of non-noble birth from entering the nobility (
heretats). Many members of the Sardinian parliament visited the
Corts of Catalonia and were familiar with its functioning. The
Corts in turn seems to have regarded Sardinia as lying within its jurisdiction, for in 1366 it petition Peter IV to revoke the law of exclusion passed in 1355. The king refused on the grounds that it was not right for laws passed by the parliament of one kingdom to be revoked by the parliament of another. This was relevant to Peter's other dispute with the Catalans, who wished to be exempted from the Sardinian customs regime. So long as Catalans were residents of the island they were subject to its parliament's laws. In 1420, Alfonso convened a meeting at
Bonifacio of representatives of the baronage, the church and the cities of
Corsica, but this institution did not develop and Aragonese control of Corsica—together with Sardinia forming the
regnum Sardiniae et Corsicae—soon waned. Shortly after his accession,
Ferdinand II had his
viceroy, Ximene Pérez Scrivá, summon parliament to
Oristano (November 1481), the site of a recent rebellion. The parliament was later moved to
Cagliari and then
Sassari. The purpose of this assembly was to raise monies—Pérez requested a permanent annual tax rate of one
ducat per household—for the island's defence from the
Ottoman Turks, who had
captured Otranto the year before. The weakness of the Sardinian parliament was displayed in these events. Pérez was removed because of a dispute with the citizens of Cagliari, and the reinstated a short time later, after the intervening viceroy had died. The parliament did not protest, nor did it protest when Ferdinand summoned it to Spain, where it met in
Seville and
Córdoba in the fall of 1484. The Sardinian elite, mostly descended from Catalans, maintained strong ties with Spain. The final
procès-verbal of the meeting in Seville on 27 October declared that the "decrees, provisions, commissions and other acts granted by His Majesty to the estates of said kingdom ... will remain in suspension and suspended until the grants of money of the said estates are published by His Majesty in the said kingdom of Sardinia." ==Spanish era==
