Category:TTPI Period (1947-1979)

Following liberation of the islands in the War in the Pacific, the islands were initially administered by the US Navy during the USN Period (1945-1947). The Trust Territory of the Pacific Islands (TTPI) was formalized by United Nations Security Council in 1947.

The same year, responsibility for the civil administration of the trust territory was delegated to the Navy on an interim basis. The Navy passed governing duties to the Department of the Interior in 1951, formatting DOI's role, which would continue throughout the remainder of TTPI Period (1947-1979).
