The present country of Tanzania, officially the United Republic of Tanzania, was created upon the union of the formerly independent countries of Tanganyika and the People's Republic of Zanzibar (P.R.Z.).

Tanganyika became independent from the United Kingdom (U.K.) on December 9, 1961. The United States (U.S.) immediately recognized the new nation and moved to establish diplomatic relations. The U.S. embassy in Dar es Salaam opened on the day of Tanganyika's independence. William R. Duggan served as the chargé d'affaires ad interim pending the appointment of an ambassador.

The Sultanate of Zanzibar became independent from the U.K. on December 19, 1963, as a constitutional monarchy headed by its sultan. The U.S. established an embassy in Zanzibar on December 10, 1963, with Frederick P. Picard III serving as chargé d'affaires ad interim. In January 1964, the sultan was overthrown and the P.R.Z. was established.

On April 26, 1964, Tanganyika united with the P.R.Z. to form the United Republic of Tanganyika and Zanzibar (U.R.T.Z.). The U.S. ambassador to Tanganyika, William Leonhart, immediately became the ambassador to the U.R.T.Z. A U.S. ambassador to the P.R.Z. had not yet been appointed when that country united with Tanganyika. In lieu of an ambassador, Frank C. Carlucci III was serving as the chargé d'affaires ad interim and continued in that capacity until the U.S. embassy was downgraded to a consulate general on June 27, 1964.

The country was renamed the United Republic of Tanzania on October 29, 1964.

The U.S. did not have an ambassador to Tanzania from October 2016 to August 2020.[1]

Ambassadors

U.S. diplomatic terms

Career FSO
After 1915, The United States Department of State began classifying ambassadors as career Foreign Service Officers (FSOs) for those who have served in the Foreign Service for a specified amount of time.

Political appointee
A person who is not a career foreign service officer, but is appointed by the president (often as a reward to political friends).

Appointed
The date that the ambassador took the oath of office; also known as "commissioning". It follows confirmation of a presidential appointment by the Senate, or a Congressional recess appointment by the president. In the case of a recess appointment, the ambassador requires subsequent confirmation by the Senate to remain in office.

Presented credentials
The date that the ambassador presented his letter of credence to the head of state or appropriate authority of the receiving nation. At this time the ambassador officially becomes the representative of his country. This would normally occur a short time after the ambassador's arrival on station. The host nation may reject the ambassador by not receiving the ambassador's letter, but this occurs only rarely.

Terminated mission
Usually the date that the ambassador left the country. In some cases a letter of recall is presented, ending the ambassador's commission, either as a means of diplomatic protest or because the diplomat is being reassigned elsewhere and replaced by another envoy.

Chargé d'affaires
The person in charge of the business of the embassy when there is no ambassador commissioned to the host country.

Ad interim
Latin phrase meaning "for the time being", "in the meantime".
