In 1832, 1838 and 1854, Perugia was hit by earthquakes. Following the collapse of the Roman republic of 1848-49, when the Rocca was in part demolished, it was seized in May 1849 by the Austrians. In June 1859, the people rebelled against the temporal authority of the Pope and established a provisional government, but the insurrection was quashed bloodily by Pius IX's troops. In September 1860 the city was united finally, along with the rest of Umbria, as part of the Kingdom of Italy.
