Alexandru Vaida-Voevod in the context of "Romanian Old Kingdom"

The National Peasants' Party (also known as the National Peasant Party or National Farmers' Party; Romanian: Partidul Național Țărănesc, or Partidul Național-Țărănist, PNȚ) was an agrarian political party in the Kingdom of Romania. It was formed in 1926 through the fusion of the Romanian National Party (PNR), a conservative-regionalist group centred on Transylvania, and the Peasants' Party (PȚ), which had coalesced the left-leaning agrarian movement in the Old Kingdom and Bessarabia. The definitive PNR–PȚ merger came after a decade-long rapprochement, producing a credible contender to the dominant National Liberal Party (PNL). National Peasantists agreed on the concept of a "peasant state", which defended smallholding against state capitalism or state socialism, proposing voluntary cooperative farming as the basis for economic policy. Peasants were seen as the first defence of Romanian nationalism and of the country's monarchic regime, sometimes within a system of social corporatism. Regionally, the party expressed sympathy for Balkan federalism and rallied with the International Agrarian Bureau; internally, it championed administrative decentralization and respect for minority rights, as well as, briefly, republicanism. It remained factionalized on mainly ideological grounds, leading to a series of defections.

With its attacks on the PNL establishment, the PNȚ came to endorse an authoritarian monarchy, mounting no resistance to a conspiracy which brought Carol II on the Romanian throne in 1930. Over the following five years, Carol manoeuvred against the PNȚ, which opposed his attempts to subvert liberal democracy. PNȚ governments were in power for most of the time between 1928 and 1933, with the leader Iuliu Maniu as its longest-serving Prime Minister. Supported by the Romanian Social Democrats, they expanded Romania's welfare state, but failed to tackle the Great Depression, and organized clampdowns against radicalized workers at Lupeni and Grivița. This issue brought Maniu into conflict with the outlawed Romanian Communist Party, though the PNȚ, and in particular its left, favored a Romanian popular front. From 1935, most of the centrist wing embraced anti-fascism, outvoting the PNȚ's far-right, which split of as a Romanian Front, under Alexandru Vaida-Voevod; in that interval, the PNȚ set up pro-democratic paramilitary units, or Peasant Guards. However, the party signed a temporary cooperation agreement with the fascist Iron Guard ahead of national elections in 1937, sparking much controversy among its own voters.

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 Romanian Front (Romanian: Frontul Românesc, FR) was a fascist party created in Romania in 1935. Led by former Prime Minister Alexandru Vaida-Voevod, it originated as a right-wing splinter group from the mainstream National Peasants' Party (PNȚ). While in power, Vaida had an ambiguous approach to the Iron Guard, and constructed his own radical ideology; the FR had a generally xenophobic program of positive discrimination, being implicitly (and eventually explicitly) antisemitic. It was subsumed to the policies of King Carol II, maneuvering between the mainstream National Liberals, the PNȚ's left-wing, and the more radically fascist Guardists. Vaida tried to compete with the former two and appease the latter, assuming fascist trappings such as the black-shirted uniform. Like the Guard, he supported aligning Romania with the Axis powers, though he also hoped to obtain their guarantees for Greater Romania's borders. The FR's lower echelons included Viorel Tilea and other opponents of Vaida's approach, who believed in Romania's attachments to the League of Nations and the Little Entente.

Albeit invested with the king's trust and counting experienced politicians among its cadres, the FR was always a minor force in Romanian politics, and was habitually defeated in by-elections. Its peak influence was recorded during the local elections of June 1937, when it emerged as the second most popular party in Ilfov County. Early on, it was courted by other radical groups, narrowly failing to absorb the National Agrarian Party. It came to depend on the more powerful National Christian Party, with which it formed a political alliance in 1935. Called "National Bloc", it too failed to produce a full merger between its components, as Vaida had qualms about the unchecked Germanophilia of his partners; his Romanianization project was also regarded as too mild by National Christian standards. In later years, the FR made several sustained efforts to reunite with, or to absorb, the "centrist" wing of the PNȚ.
