In Charles Albert's reign the house of Savoy became the center of the Risorgimento, the movement that led to the unification of Italy under his son, Victor Emmanuel II. Savoy itself, however, was ceded to France in 1860. Humbert I, who succeeded (1878) Victor Emmanuel II as king of Italy, was assassinated in 1900. His son and successor, Victor Emmanuel III, also took the titles emperor of Ethiopia (1936) and king of Albania (1939); after the Italian armistice (1943) with the Allies in World War II he delegated (1944) his powers to his son, who briefly ruled (1946) as Humbert II from Victor Emmanuel's abdication until the establishment of the Italian republic, when the family went into exile. Male members of the family were barred from entering Italy from 1948 to 2002.
