The Estonian National Independence Party, commonly abbreviated ERSP, was a nationalist political party founded on 20 August 1988 in what was then the Estonian SSR. Founders of the party were nationalist and anti-Communist dissidents. The initiative to establish Estonian National Independence Party came from Vello Väärtnõu, the leader of an Estonian Buddhist Brotherhood group. On 30 January 1988 he organized a press conference in Moscow for Western media where he announced the formation of ENIP, aimed at re-establishing independence of the Estonian Republic as a nation state on the restitution principle. This made the ENIP the most radical or political movement of its day. Vaartnou and fellow Buddhists were expelled from the Soviet Union shortly after the press conference and ENIP was officially founded in August 1988 in Pilistvere.
