The regime remained chiefly "neutral" from a nominal standpoint in the Second World War (it briefly switched its position to "non-belligerent"), although it was sympathetic to the Axis and provided the Nazi Wehrmacht with Spanish volunteers in the Eastern Front. The only legal party under Franco's dictatorship was the Falange Española Tradicionalista y de las JONS (FET y de las JONS), formed in 1937 upon the merging of the Fascist Falange Española de las JONS and the Carlist traditionalists and to which the rest of right-wing groups supporting the rebels also added. The name of "Movimiento Nacional", sometimes understood as a wider structure than the FET y de las JONS proper, largely imposed over the later's name in official documents along the 1950s.
