Sardinians, headed by Giovanni Maria Angioy, start a revolution against the Savoy domination, expelling Viceroy Balbiano and his officials from Cagliari, the capital and largest city of the island.

Sardinians or Sards are an ethno-linguistic group indigenous to Sardinia, an island in the western Mediterranean which is administratively an autonomous region of Italy.

Giovanni Maria Angioy was a Sardinian politician and patriot and is considered to be a national hero by Sardinian nationalists. Although best known for his political activities, Angioy was a university lecturer, a judge for the Reale Udienza, an entrepreneur and a banker.

The House of Savoy is a royal house of Franco-Italian origin that was established in 1003 in the historical region of Savoy, which was originally part of the Kingdom of Burgundy and now lies mostly within southeastern France. Through gradual expansions, the family grew in power, first ruling the County of Savoy, a small Alpine county northwest of Italy, and later gaining absolute rule of the Kingdom of Sicily. During the years 1713 to 1720, they were handed the Kingdom of Sardinia and would exercise direct rule from then onward as Piedmont–Sardinia, which was the legal predecessor state of the Kingdom of Italy, which in turn is the predecessor of the present-day Italian Republic.
