مؤتمر الجزيرة الخضراء
On March 6, 1905, White received his long-awaited promotion to Ambassador, as President Roosevelt named him to represent the United States with Italy. While Ambassador to Italy, White served as the lead U.S. mediator during the 1906 Algeciras Conference. The agreement reached during that conference averted a war between France and Germany over economic rights in Morocco.
