Samoa / Tupua Tamasese Mea'ole and Malietoa Tanumafili II

When Samoa became independent on January 1, 1962, two of the four paramount chiefs (Tama a 'Aiga) - Tanumafili II and Meaʻole - were jointly named to the office for life by the 1960 Constitution. Each represented, respectively, the Malietoa and Tupua Tamasese, the "two of the four main family lineages" of Samoa.

They were jointly known as O Ao o le Malo and individually as O le Ao o le Malo. Mea'ole died a year later in 1963, leaving Tanumafili as the sole holder of the office until his death in 2007, aged 94.
