The Nationale Aktion was in origin a far rightxenophobic movement pursuing an anti-immigration agenda during the 1960s. After a hostile split with James Schwarzenbach in 1971, the movement lost most of its momentum during the 1970s. It re-surfaced in the 1980s.After another hostile split with former president Valentin Oehen, it was renamed to its current name in 1990. After 1998, the party lost nearly all significance in national politics because of the absorption of far right votes into the growing Swiss People's Party.
