The flag of the Federated States of Micronesia (FSM) was adopted on November 10, 1979. The blue field represents the Pacific Ocean, while the four stars represent the four island groups in the federation: Chuuk, Pohnpei, Kosrae, and Yap.
A similar design with six stars was in use from 1965 for the flag of the Trust Territory of the Pacific Islands, the extra stars representing Palau, the Marshall Islands and Northern Mariana, which chose not to participate in the Federation. (Kosrae was then part of Pohnpei, so one star represented both.) The flag, adopted in 1978, is in the colors of the UN flag. The light blue also represents the Pacific Ocean. In an echo of US practice, the stars represent the four islands, arranged like the points of the compass.
