The Falange Española Tradicionalista y de las Juntas de Ofensiva Nacional Sindicalista, frequently shortened to just "FET", was the sole legal party of the Francoist regime in Spain. It was created by General Francisco Franco in 1937 as a merger of the fascist Falange Española de las JONS with the monarchist neo-absolutist and integralist Catholic Traditionalist Communion belonging to the Carlist movement. In addition to the resemblance of names, the party formally retained most of the platform of FE de las JONS and a similar inner structure. In force until April 1977, it was rebranded as the Movimiento Nacional in 1958.

Francoist Spain, also known as the Francoist dictatorship, was the period of Spanish history between 1936 and 1975, when Francisco Franco ruled Spain after the Spanish Civil War with the title Caudillo. After his death in 1975, Spain transitioned into a democracy. During this time period, Spain was officially known as the Spanish State.
