It was founded on 22 April 2005 by John Momis, Governor of Bougainville Province from 1999 to 2005, with former Premier Alexis Sarei among other figures involved in its creation.
[1][2] Momis lost the 2005 presidential election to Joseph Kabui and resigned the party leadership, which was assumed by Ezekiel Massat.
The party immediately formed a grand coalition with Kabui's Bougainville People's Congress, citing a desire to show that the province was "politically rising".
[5] In December 2007, government ministers Massat and Patrick Nisira resigned from the party to sit as independents in protest at a motion by their colleagues for the establishment of a formal opposition in Bougainville.
[6] The party endorsed Raymond Hakena, a former member of 1980s band Sanguma, in the 2008 presidential by-election after Kabui's death, but lost to James Tanis.
