The flag of the Federated States of Micronesia 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, Ponape, Kusaie and Yap.
A similar design with six stars was in use from 1965 for 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. (Kusaie was then part of Ponape so both were represented by one star.)
