After the revolutions and the Trianon Peace Treaty, political life in Hungary continued to face several challenges. This study presents the political atmosphere that resulted the 1922 National Assembly election and its results. Berettyóújfalu was one of the constituencies affected by the new national border. Lajos Szilágyi applied for a mandate as a representative here. He was considered by the public of the time to be an active opposition politician. The United Party, led by István Bethlen and István Nagyatádi Szabó, also entered the fight for representative mandates. The ruling party exerted a lot of power to get its own candidates a mandate, as well as to obstruct the campaign of opposition politicians. This thesis seeks the answer to the question of how the campaign of the United Party took place in the electoral district of Berettyóújfalu, and how this series of events fits into the national election preparations of the governing party
