مؤتمر الجزيرة الخضراء
After graduating in law from the University of Pisa, Sforza entered the diplomatic service in 1896. He served as consular attaché in Cairo (1896) and Paris (1897), then as consular secretary in Constantinople (1901) and Beijing. He was then appointed chargé d'affaires in Bucharest in 1905, but a diplomatic incident caused him to resign in December of the same year. Nevertheless, he was sent as private secretary of Marquis Emilio Visconti-Venosta, the Italian delegate to the Algeciras Conference.
