Gherardo della Gherardesca

Gherardo della Gherardesca was the youngest son of Count Ranieri della Gherardesca, il Vecchio. On his brother Bernabò's death he inherited the title count of Donoratico and his family's Sulcis fiefs in Sardinia.

In September 1353, early in the Sardo-Catalan war, Arborean commanders captured him and Judge Mariano IV persuaded him to back Arborea. He died in Sardinia in January 1355, after which King Peter IV of Aragon sentenced him posthumously for treason and confiscated all his lands.
