diplomat, minister of foreign affairs in the cabinet of Benedetto Cairoli (1878–88), and Italian representative at the Congress of Berlin (1878–79), for which he received much criticism, probably undeserved.

Corti interrupted his diplomatic career, begun in the Piedmontese service (i.e., that of the kingdom of Sardinia) in 1846, to volunteer in the war between Piedmont and Austria (1848). After the war he was appointed secretary of the Piedmontese, later Italian, legation in London (1850), where he remained until his appointment as minister in Stockholm (1864). He then held a succession of diplomatic posts until March 1878, when he reluctantly accepted the post of minister of foreign affairs in Cairoli's leftist cabinet, with which Corti was not entirely sympathetic.

Just before the Congress of Berlin (Berlin, Congress of), called by the European powers to revise a punitive treaty forced on Turkey by Russia, Corti undertook some profitless negotiation with England about Balkan affairs. At Berlin, he and his colleagues could not prevent Austrian occupation of Bosnia-Hercegovina; nor did they take steps that might have prevented the later French occupation of Tunisia. Censured by their countrymen, their actions were largely the result of poor communication with Cairoli's cabinet.

Corti resigned his post (October 1878) but was appointed ambassador to Turkey in 1880. Transferred to London in 1886, he was recalled in October 1887 to Rome, where he died a few months later.
