Sección Femenina (Women's Section) was the women's branch of the Falange political movement in Spain. Founded in 1934, it subsequently became an official institution in the Francoist era. Following General Franco's death and the beginning of the transition to democracy it was disbanded on 1 April 1977 together with all Movimiento Nacional institutions. Sección Femenina was led throughout its history by Pilar Primo de Rivera, the younger sister of Falange founder José Antonio Primo de Rivera.
Sección Femenina was conceived from the beginning as an extension of the domestic role of women to the public sphere, though it took part in political activities during the 1936 election's campaign. During the Second Republic the members of Sección Femenina supported the male Falangists in tasks such as paying visits to imprisoned members and their families. Following the breakout of the Civil War in 1936 they supported the families of those killed in the National faction and took care of the basic assistance to the population of conquered cities. In 1937 Sección Femenina became an official institution as Franco entrusted it the organization of Servicio Social de la Mujer (Social Service for Women), a compulsory female equivalent of the Francoist military service centered in housework. The Castle of La Mota in Medina del Campo, Valladolid served as its headquarters from 1942.
Initially Sección Femenina was organised in three delegaciones: Movimiento femenino (led by Pilar Primo de Rivera), Auxilio Social (led by Mercedes Sanz Bachiller, the widow of Onésimo Redondo) and Frentes y Hospitales (led by María Rosa Urraca Pastor). The three leaders did not work together well. Following constant clashes with Primo de Rivera Urraca resigned in 1938 and Sanz was marginalized after the Civil War.
