In August 1870, he took part in the republican insurrection against the Hohenzollern Domnitor, Carol I, in Ploieşti. The movement was suppressed and he was charged along with 40 other people, but the Târgovişte court of law acquitted them. In his tongue-in-cheek account of the insurrection (Boborul), Ion Luca Caragiale identified Candiano-Popescu with the "Republic's president", and claimed that he had appointed several of his collaborators into high office.
In 1877, as the War of Independence against the Ottoman Empire began, Candiano, although he was a deputy in the Romanian Parliament, joined the army to take part in the assault over Grivitsa, being the commander of the 2nd Hunters' Battalion, receiving the Order of St. George from Alexander II, the Emperor of Russia. In 1880, he became Carol's Adjutant, a position he held for 12 years. In 1894, he was named General of Cavalry.
He wrote a volume of poetry, Când n-aveam ce face (1866), and several war songs.
