Pacte de Bagdad
Nabulsi entered his party into an electoral alliance with the Jordanian Regional Branch of the Ba'ath Party and Jordanian Communist Party to form the National Front (NF) which called for freeing Jordan of foreign influence, political, economic, and military cooperation with Arab nationalist states, and aiding other Arab states with their fight against imperialism. They failed in their attempt to gain a majority in the 40-member Jordanian parliament, allegedly due to poll rigging by King Hussein's allies. However, they did win twelve seats, making it the largest bloc, and as leader of the NF, Nabulsi managed to prevent Jordan from entering the Central Treaty Organization (Baghdad Pact) alliance in 1955, then succeeded in getting Hussein to dissolve the parliament.
