This group of Samoans were forcibly exiled to Saipan by their German colonial overlords in 1904 for daring to question the occupation of their home islands.  The Japanese, of all people, liberated them in 1915 as part of their campaign to take over German Pacific Island outposts.  This little known element of World War I left the Japanese in control of some strategic islands that the Americans in turn took from them in World War II.  That sort of mess just goes on and on, doesn't it?
