The Stamenti (Spanish: Estamentos; Catalan: Estaments; Sardinian: Istamentos / Stamentus) was the parliament of Sardinia, consisting of representatives of the three estates of the realm.
The term "Stamenti" is the plural of "Stamento" and they are both forms which, under Savoyard rule, were Italianized from the original Spanish word "Estamento", which referred to an estate of the realm.
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.
[6] 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 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.
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.
It was regularly called every nine or ten years to approve taxes, but as the costs of Spain's foreign wars rose in the early seventeenth century it became increasingly reluctant to grant the king's proposed expropriations.
At one point Vivas quartered Lombard soldiers in his opponents' houses to break their opposition, but for the most part each side merely delivered grievances to the Council of Aragon in Spain.
The parliament—or at least the faction led by the local nobility—disputed the king's right to appoint Spaniards to public office in Sardinia, defended noble jurisdiction against royal encroachment, asserted the right of cities to export grain without first storing it in government granaries and demanded that the king confirm all the acts previously passed by parliament.
This brought Sardinia in line with the other possessions of the House of Savoy, save the Duchy of Aosta, the last one where parliamentary approval was still required for raising money.
