The Kingdom of Sardinia is a country located in southern Europe. The capital is Rome.
The Kingdom of Sardinia, also known as Piedmont-Sardinia or Sardinia-Piedmont, was the name given to the possessions of the House of Savoy in 1720, when the crown of Sardinia was awarded by the Treaty of The Hague to Duke Victor Amadeus II of Savoy to compensate him for the loss of the crown of Sicily to Austria, retaining in that way the title of king. Besides Sardinia, the new kingdom included Savoy, Piedmont and Nice.
