The UPR was registered on 16 March 1990. Xenia Grabska-Stoica was the first president of the union, and Andrei Răuță and Mihai Rainer were the deputy-presidents; Antoni Rojowski was the first chairman. The party contested the
May 1990 general elections, and despite receiving only 2,372 votes (0.02%), it won a single seat in the
Chamber of Deputies (taken by
Antoni Linzmeier) under the electoral law that allows for political parties representing ethnic minority groups to be exempt from the
electoral threshold. At the party congress held in Suceava on 13 and 14 April 1991, Rojowski was re-elected president, serving until 1994. The headquarters of the organisation were moved to Suceava shortly afterwards. Antoni Rojowski was president until 1994. Iohan-Peter Babiaș served as president from 1994 until 2002. He was succeeded by
Ghervazen Longher. In 2013, after hiring his brother and sister to his parliamentary office, Longher was convicted. In the
2016 elections Victoria Longher, the wife of Ghervazen, was elected to parliament on as the party's representative. == Structure ==
