The flag of the Trust Territory of the Pacific Islands (TTPI) consisted of a light blue field that contained six white stars centered in a circle pattern. The stars symbolized the six districts of the former trusteeship: the Marianas, the Marshall Islands, Yap, Chuuk, Pohnpei, and Palau. The blue field symbolized freedom and loyalty.
The flag was the end product of a contest that was won by Gonzalo Santos, a government employee who lived in the Yap district. For his efforts, he won US$250. The Santos design was approved by the Council of Micronesia (an unofficial body) on October 3, 1962, and was first used on October 24. The flag was reapproved by the TTPI High Commissioner and the Congress of Micronesia in July 1965. The flag became official on August 19, 1965.
Before this time, the United States and United Nations flags were used in the trusteeship.
The flag was used until the early to late 1970s and early 1980s. By this time, each district of the TTPI had adopted its own unique flag.
