The Romanian National Party (Romanian: Partidul Național Român, PNR), initially known as the Romanian National Party in Transylvania and Banat (Partidul Național Român din Transilvania și Banat), was a political party which was initially designed to offer ethnic representation to Romanians in the Kingdom of Hungary, the Transleithanian half of Austria-Hungary, and especially to those in Transylvania and Banat. After the end of World War I, it became one of the main parties in Romania, and formed the government with Alexandru Vaida-Voevod between November 1919 and March 1920.
The party was formed on May 12, 1881 as the union of the National Party of Romanians in Transylvania (Partidul Național al Românilor din Transilvania) and the National Party of Romanians in Banat and Hungary (Partidul Național al Românilor din Banat și Ungaria), both created in 1869 (two years after the Austro-Hungarian Compromise of 1867). Its policies were connected with Liberalism and the Romanian middle class, and challenged the centralism of the Budapest government, calling for an end to Magyarization policies and a more representative Hungarian Parliament (as the suffrage was still wealth-based, thus favoring the Transylvanian Hungarians over an initially largely peasant Romanian population).
