If you mean the two countries, they are Samoa (formerly known as Western Samoa) and American Samoa or Tutuila, known also as Eastern Samoa.
it is called western Samoa because Samoa is divided into two parts, American Samoa and western Samoa. After colonialism came to Samoa, America took control of Eastern Samoa which adapted the name "American Samoa". While Germany (and later NZ) took control of Western Samoa, who then took on the name "Western Samoa". No called SAMOA. The nation dropped the "western" in 1997.
Samoa and American Samoa
yes it is actually. the top of Samoa is called Samoa and the bottom of Samoa is called Upolu.
It used to be one whole country. Samoa. Until world war I when the US occupied American Samoa for its naval base in Pago Pago, and Western Samoa was occupied by Germany, and then NZ. Now, Samoa (no longer called Western Samoa) is an independent country, whereas American Samoa is still a US territory (but is governed by Samoan representatives and a Samoan Governor). So now there is American Samoa and Samoa.
Because Apia is the captial of Upolu IN Samoa (the two island Upolu & Savaii)
Samoa and American Samoa
The Two Samoas are American Samoa and Western Samoa. Western Samoa is consisted of the two islands Upolu and Savaii. Between those two islands, Savai'i is the largest.It is NOT called WESTERN SAMOA. Just Samoa. There are seven islands in total in Samoa. But only 3 of which are occupied by Samoan people. The largest is Savaii, followed by Upolu. Then you have Apolima (which is the 3rd inhabited island), Manono, Nuulua, Nuutele, Namua and Fanuatapu.Well, some people, such as I, say "Western Samoa" when referring to Western Samoa.Well people such as yourself and anyone else who does not know should read up on their countrys' history. It's NOT called Western Samoa anymore and hasn't been called that since the Prime Minister and government changed its official name in the early 1990's. It's official name is now SAMOA.
