The base of the flag of Nauru, the smallest independent country in the world, which has been adopted in 1976 when the country achieved independence, consists of a dark blue sheet. The sheet is crossed by a yellow stripe in its middle and below the stripe and closer to the left part of the flag a twelve-pointed white star is placed. Each chip represents one of the twelve tribes that used to inhabit the island, although two of them do not exist already. Yellow stripe symbolizes the equator and the star depicts the position of the island against the equator. The blue color of the sheet should remind the Pacific Ocean, which surrounds the island. The design of the flag was chosen through a public competition, where a draft of an Australian designer won.
