|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.
The island of Sardinia, for which the kingdom is named, is, ironically, the least integrated part of the Kingdom, enjoying considerable autonomy.
