A Guide to the United States’ History of Recognition, Diplomatic, and Consular Relations, by Country, since 1776: Nauru
After several colonial and military occupations, Nauru became a United Nations trust territory following World War II. The country achieved independence in 1968, and several years later the United States accredited its Ambassador to Australia to also serve Nauru. The United States does not have an embassy in the Yaren District; today, the U.S. Ambassador to Fiji is accredited to Nauru.
Establishment of Diplomatic Relations, 1976.
Diplomatic relations were established on October 24, 1976, when U.S. Ambassador to Australia Marshall Green presented his credentials to Nauru; he remained resident at Canberra.
