# Johann, 2nd Prince of Khevenhüller-Metsch

Johann Sigismund Friedrich, 2nd Prince of Khevenhüller-Metsch (22 February 1732 – 15 June 1801) was an Austrian prince and diplomat.

## Early life

Born Johann Sigismund Friedrich von Khevenhüller on 22 February 1732 in Vienna, he was the second born, but eldest surviving, son of Johann, 1st Prince of Khevenhüller-Metsch (1706–1776) and Countess Karolina Maria Augustina von Metsch (1706–1784). His father was a diplomat during the early reign of Empress Maria Theresa, serving as the Habsburg Ambassador to Denmark, Saxony, and as the Bohemian Ambassador to the Perpetual Diet of Regensburg.
His paternal grandparents were Count Sigmund Friedrich von Khevenhüller and, his second wife, Ernestine Leopoldine von Orsini-Rosenberg. His maternal grandfather was Imperial Vice-Chancellor (German: Reichsvizekanzler) Count Johann Adolf von Metsch. As his maternal grandfather had no male issue, he adopted his father, who took Metsch as an additional surname in 1751.

## Career

His father was created 1st Prince of Khevenhüller-Metsch in 1763. The family owned Riegersburg Castle in Hardegg and Ladendorf Castle in Lower Austria. Following his death on 18 April 1776, he succeeded as the 2nd Prince of Khevenhüller-Metsch and as Hofmeister from Lower Austria. He was also Prince of Aichelberg, Count of Hohen-Osterwitz and Annabüchl, Baron of Landskron and Wernberg, and Hereditary Lord of Carlsberg.
A diplomat like his father, he served as the Habsburg Ambassador to Portugal from 1756 to 1760, the Kingdom of Sardinia-Piedmont in Turin from 1763 to 1770, and Plenipotentiary Commissioner-General to the Duchy of Milan from 1775 to 1782, the Emperor Joseph II's highest representative in Imperial Italy. After his service in Milan, he retired from diplomatic service, and lived mainly in his Palace in Milan (designed by Italian architect Giuseppe Piermarini on Via Monte di Pietà, no. 1A) and other Italian cities before returning to Austria in 1801 shortly before his death.
He was made a Knight of the Order of the Golden Fleece.
