Sardinian nationalism or also Sardism (Sardismu in Sardinian; Sardismo in Italian) is a social, cultural and political movement in Sardinia calling for the self-determination of the Sardinian people in a context of national devolution, further autonomy in Italy, or even outright independence from the latter. It also promotes the protection of the island's environment and the preservation of its cultural heritage. Even though the island has been characterized by periodical waves of ethnonationalist protests against Rome, the Sardinian movement has its origins on the left of the political spectrum; regionalism and attempts for Sardinian self-determination historically countered in fact the Rome-centric Italian nationalism and fascism (which eventually managed to contain the autonomist and separatist tendencies). Over the years many Sardist parties from different ideological backgrounds have emerged (even on the right and the centre), all being in the minority, and with some of them making government coalitions of variable geometry with the statewide Italian parties. For instance, that also happened in the 2014 Sardinian regional election, where the combined result of all the nationalist parties had been 26% of the votes. In 1720, the Kingdom of Sardinia was definitely ceded by Spain to the House of Savoy after a plurisecular period of Spanish rule and a short-lived reconquest, abiding by the treaty of London that followed the War of Spanish Succession. The Savoyard kings, who were forced to accept this island in place of the much more populated and profitable Sicily, were not pleased with the exchange to the point of making them want to dispose of what Cavour called "the third Ireland" later, according to Mazzini who denounced part of the plot, by repeatedly trying to sell it to either Austria or France. For a long time, Sardinia would be ruled in the same way as it was during the Spanish period, with its own parliament and government being composed exclusively of men from the Mainland.
