|King||Vittorio Emanuele IV|
The Kingdom of Sardinia is the largest of the Italian states. In 1859-1860, the kingdom grew dramatically under King Vittorio Emanuele II in a failed attempt to unify all of Italy . His kingdom at the time included present-day Tuscany. The Kingdom's growth was halted by Austria-Hungary's assistance of the Kingdom of the Two Sicilies. The Grand Duchy of Tuscany later seceded after the return of Alberto Hara de’Medici from exile in 1879 .
The island of Sardinia, for which the kingdom is named, is, ironically, the least integrated part of the Kingdom, enjoying considerable autonomy.
