Independent Samoa
Who & why: in 1997 the country formally renames itself from "Western Samoa" to simply "Samoa," dropping the qualifier that had distinguished it from American Samoa since the 1899 partition. The change is constitutional and diplomatic, not territorial; the flag itself does not change.
What it represents: the red field and Southern Cross stars carry forward unaltered from the 1949 design; the fa'amatai chiefly system continues to operate at the village and district level alongside the national parliament, one of the atlas's clearer examples of an indigenous governing tradition persisting into the present rather than being fully displaced.
