The House of Savoy is an Italian royal house that was established in 1003 in the historical Savoy region. Through gradual expansion, the family grew in power from ruling a small Alpine county north-west of Italy to absolute rule of the Kingdom of Sicily from 1713 to 1720, when they were handed the island of Sardinia, over which they would exercise direct rule from then onward.

The County of Savoy was a state of the Holy Roman Empire which emerged, along with the free communes of Switzerland, from the collapse of the Burgundian Kingdom in the 11th century. It was the cradle of the future Savoyard state.
