A Roman Republic was declared in February 1849. Pius responded from his exile by excommunicating all participants.[4] After the suppression of the republic later that year, Pius appointed a conservative government of three cardinals known as the Red Triumvirate to administer the Papal States until his return to Rome in April 1850.[5] He visited the hospitals to comfort the wounded and sick, but he seemed to have lost both his liberal tastes and his confidence in the Romans, who had turned against him in 1848.[citation needed] Pius decided to move his residence from the Quirinal Palace inside Rome to the Vatican, where popes have lived ever since.[6]
