#malo saʻoloto tutoʻatasi o sāmoa

Samoa has the distinction of being the first formerly colonized nation in the Pacific to gain independence - in 1962 from the British/New Zealand.  Prior to that, it had been under German control there for a while, with the UK and USA bickering about who gets what for a time before that [thus: American Samoa].  After independence, as Western Samoa, the Samoans decided to drop the “Western” in the late 1990s (to great outrage on their American Samoan neighbors’ part, who took umbrage at the apparent attempt to claim true Samoanness).
