Your Highness, le Afioga a le Tui Atua Tupua Tamasese Ta’isi Tupuola Tufuga Efi

Tupua was born on 1 March 1937 at Moto'otua in Samoa and attended primary school at the Marist Brothers School at Mulivai in the Samoan capital of Apia. He continued his education at St. Patrick's College in Silverstream, Wellington, New Zealand. He was also educated at Victoria University of Wellington, New Zealand.

Tupua began his political career in 1966 when he became an MP in Samoa's Fono, or Parliament. He represented the Anoama'a East constituency as MP as a member of the Christian Democratic Party. He served as Samoa's Minister of Works from 1970 until 1972.

Tupua served as Prime Minister for two consecutive terms from 1976 to 1982. He also served as Deputy Prime Minister from 1985 to 1988. It was during his second term as Prime Minister that the Public Service Association went on a general strike in 1981, paralysing the country for several months and paving the way for the opposition Human Rights Protection Party's entry to government in 1982; the party was in power as of 2013.

Tupua became Leader of the Opposition following his Christian Democratic Party's election defeat in 1982. He also headed the Samoan National Development Party. He continued to serve Anoama'a East as MP until 2004 when he became one of the two members of Samoa's Council of Deputies along with Tuimaleali'ifano Va'aletoa Sualauvi II. Both Tupua and Va'aletoa served as temporary acting heads of state (O le Ao o le Malo) following the death of Malietoa Tanumafili II in May 2007.
