History
November 1976 – Ukrainian community groups was established to promote the implementation of the Helsinki agreements. Almost all members of this Ukrainian Helsinki Group were subsequently repressed; four of them (V. Stus, Yu. Lytvyn, O. Tykhyi, V. Marchenko) died in Soviet camps.
March 1988 – Ukrainian Helsinki Union (UKhS) was formed. Since 1989, UKhS has moved to open propaganda activity, promoting the independence of Ukraine.
April 29–30, 1990 – Ukrainian Republican Party (URP) was established in the place of the UKhS. The party was registered on November 5, 1990 by the Ministry of Justice of the Ukrainian SSR as the first political party in Ukraine.
On 15 October 2012 the party withdrew itself from the national list of the 2012 Ukrainian parliamentary election.[17] In the election it did not win any constituencies (it had competed in 12 constituencies[18]) and thus failed to win parliamentary representation.[19]
In the 2014 Ukrainian parliamentary election the participated in 6 constituencies; but its candidates lost in all of them and thus the party won no parliamentary seats.[20][21]
